Hello friends !! Good morning !!

Today I am going to share my experiences about the types of mistakes which I committed and their possible solutions in context of GATE 2016 and GATE 2017 wherever I can cite examples which I attempted and secured 332 rank and 613 rank respectively [ a very rare occurence I think..:) bcoz I have seen numerous examples whose rank in prev attempt is around 2000 and then around 100 or even better in next attempt ]  due to some  mistakes..I had many hopes of excelling this year but unfortunately the D-day did not work for me..So let me tell about the potential mistakes that may be committed during exam..

Mistake type 1 :

The first mistake that I am referring is related to psychological state of a student during examination..Let we have a scenario in which a student consistently does well in tests that he/she gave in the different test series..Now it is possible that expectation factor comes into picture for a student in the exam that he/she need to attempt around 60 questions at any cost..This should not happen as it will create unnecessary pressure and may be responsible for commitment of many mistakes as the paper may be difficult and hence the questions need to be attempted accordingly as is the case of set 1 paper this time..One has to overcome the panic that may be possible in the initial minutes of attempting the paper ..In short one should have expectation but not during paper solving,,The questions should be solved on the basis of difficulty..Identification of difficulty level of a question is important..

Mistake type 2:

Misreading the question : Sometimes due to lack of concentration , what we do we misinterpret the question.The gate paper setters are very intelligent and they intentionally give such options such that the option corrresponding to misinterpretation will be there.As a result what happens we get wrong there.I used to do a lot of mistakes like that.

As an example , in a question it may say that "identify a false statement" .We do not read the entire question and understand that we have to pick the correct one thus leading to wrong result.

Mistake type 3 :

Having the default mindset regarding a question : Sometimes what happens that we have a default mindset regarding a concept or a fact being used in the question.This default or trivial  mindset often leads to error.As an example , in DBMS in normalisation , we may be asked weakest normal form of a table given the FDs of a relation.What is generally in our mind is that we have to choose the strongest i.e. the most appropriate and highest normal form which the FD set satisfies.But in question we are asked about the weakest so people may commit mistakes here.In fact this question came this year in gate,the link being:

http://gateoverflow.in/39646/gate-2016-1-23

Similarly we know about Dining Philosopher's Problem solution which is deadlock free and satisfies the criteria for proper synchronisation construct.But in exam just for name's sake it may be used but code used may suffer from problem .So we have to examine the code properly.

 

Mistake type 4:

Like question solved earlier : 

When we have similar or exact question which have solved earlier somewhere , beware of this.U have to think it as a new question and solve it properly.Some people gets overjoyed and hence commit mistakes.I did the same type of mistake on finding no of topological sort this year,

In all of the above scenarios , we should do the following :

a) We should read the whole question properly at least once , then ask to oneself what facts are given.Jot them in a piece of paper especially for numerical type questions.Else what happens is repeatedly we have to switch between paper and screen and hence time is also wasted and also one is not able to concentrate on the question.So all the important data should be mentioned like to calculate  throughput in CN we have to note down distance between stations , data size etc.

b) Then we should solve the question systematically following procedure in a proper way

c) Following answering we should verify and recheck it at least once is it the thing that is asked for.

d) Option elimination also plays an important role in some cases.Make the best use of that as it saves time.

 

Now coming to the ambiguous issue :

First of all there are 2 types of questions :

a) Conceptual and theoretical :

For this clear hold on subject is required so that u can decide whether the question is ambiguous or not within a short span of time.

b) Numerical :

Here actually there is hardly anything we can do.We have to solve after all.If after solving we find that no option is matching or more than 2 options are correct.Then we cannot do anything.Actually it rarely happens in gate , but if at all it happens , then normally marks are given to all for that.So no need to worry about that.

Sometimes from the question solving point of view setting counter example also helps.For example in problems where are we are given some statements about MST or Graph Traversals etc.There if we are able to set counter examples , it is very helpful.

 

Hope the points mentioned by me will prove to be helpful for the GATE 2018 aspirants.Thank you..

How do you people/toppers staying all day at home, self preparing,leaving out all your friends, social gatherings, get together and partying and all social media and entertainment (TV shows/movies) cope up with loneliness and live the solitary life, happily?

How do you manage when you see the whole world around you is busy partying, having fun with friends, going to malls, watching movies, cute couples, FB, Whatsapp, instagram and everything is buzzing around constantly and you on the other end your whole world is confided in your room and your books and notes!

How do deal with it and don't let this break your spirit?!

I am going to take admission in IITR with CSE branch, but I have some issues:
1. I have done B.Tech from a very low-level college, where faculties don't know anything about CS.
2. I studied just to pass the semester exams, not full syllabus but every time got the 2nd or 3rd position in batch.
3. last 4-6 months I prepared for the gate and got rank about 850.
4. My communication skill is very bad.
5. I don't know English very well even I can't explain my thought fluently in English.
6. I haven't done any project in B.tech (excluding copy paste), no training, no internship.
7. Luckily I got a job offer from Wipro.
8. I like to do coding but I am able to solve hardly 2 questions of codechef long challenge.
8. Becuase of my category (OBC-NCL) i will get IITR.

I fell that If I will be the dumbest person of IIT.
I want to know that will I survive in IIT and get a decent job with such situations?
If yes, what should I do from now?

Learning How To Learn

I took a course about "Learning How To Learn", on Coursera in which I learn about how the brain works, how to apply learning techniques and tricks to get along well with your brain, and to learn more effectively.

My short notes---

Metaphor

Metaphor and analogy help simplifying matters.

Focused vs diffuse mode-

 You’re either in the focused mode or the diffuse mode of thinking.It seems you can’t be in both thinking modes at the same time.

Focused: intense thinking, uninterruptedly
Diffuse: leave what you’re doing and relax. Here you can look at things broadly from a very different,big picture perspective.

Have you ever had a problem that you couldn’t find a solution and then suddenly after a good night of sleep you woke up with a brilliant idea? That’s because sleeping is another moment when your brain naturally falls into the diffuse mode.

Thomas Edison knew the importance of the diffuse mode. When faced with a problem, Edison would sit and relax in his chair, holding ball bearings in his hand. He would then relax away letting his mind run free until fall as sleep. Once he felt as sleep, the ball bearings would drop and make him wake up with the noise. He would then get back to his work and take advantage from the ideas he got while in diffuse mode.

 

Deal with procrastination

People tend to procrastinate, because our brains tend to turn away unease new things to something more pleasant and familiar

Use Pomodoro technique, set a timer of more than 25 minutes, uninterruptedly. Then promise to give yourself a reward.

Practice Makes Permanent

When facing new and abstract concepts, like Monad it’s important to practice with ideas and concepts to help enhance and strengthen the neural connection your making during the learning process.

Checking if you have any holes in your understanding of the material is a good first step. Create a test checklist where you can go from each point and recall everything you learned. If there’s something that is not 100% clear yet, then you probably still need to spend time on it.

Prefer spaced repetition

If you want to move that information into your long term memory, it often takes time and practice.Spaced repetition involves repeating what you’re trying to retain, but what you want to do is space this
repetition out, daily, over a number of days

 

Sleeping

Plain being awake creates toxic products in your brain, and sleeping remove these toxic. Sleeping is also when you go into your diffuse mode.

Sleep has also been shown to make a remarkable difference in your ability to figure out difficult problems and to understand what you’re trying to learn.

 

Chunking

This is the idea of breaking what you want to learn into concepts. The goal is to learn each concept in a way that they each become like a well-known puzzle piece. In order to master a concept, you not only need to know it but also to know how it fits into the bigger picture.

1 eHZ0OxiAUjYMNlSyY5K6Dg


Chunking is when you grasp and master various bits and pieces of the skills you need. You’re creating little neural mini chunks, that you can then gradually knit together into larger neural chunks.

Forming initial chunk by going through examples, creating a road map of what you need to go through--

  • Focus your undivided attention on the information you want to chunk
  • Understand the basic idea
  • See the connection between the basic elements
  • Practice and repetition

Recall

Recall instead of reread. After you’ve read the material, simply look away, and see what you can recall from the material you’ve just read

1 Qwv_V6ljhXZCGEubesLCLw

Concept mapping, drawing diagrams that show the relationship between the concepts would be the best.

Avoid illusion of competence

Merely glancing at a solution and thinking you truly know it yourself is one of the most common illusions of competence in learning.

Test it, recall it to see whether you actually grasp the idea.

By recalling and thinking about the material when you are in various physical environment, you become independent of the cues from any one given location

Avoid overlearning

Spread it out over many sessions and over many different modes of learning.

I have been trying to set aside 30–60 minutes every day for each new thing I am trying to learn or learn in more depth. Not only has this been better in resulting in lasting learning, but I also find it way more achievable to say that I am going to work on X for 30 minutes.

1 dXJcIXKipBETJ7zUI4V5hw

Continuing to study or practice after you’ve mastered what you can in the session is called overlearning.

Deliberate practice by focusing on the more difficult material.

 Each practice session should be focused on one individual skill. Usually, each skill built upon the one before it

Remember Einstellung, a phenomenon, in which an idea you already have in mind or a neural pattern you’ve already developed and strengthened, may prevent a better idea or solution from being found.

Can you recall a situation where you kept trying the same thing over and over again, even though it wasn’t working at all !!

Meaningful groups


Study Groups / Teamwork

This one isn’t new to me and has proven to be most beneficial to maintain continued progress and hold each other accountable. But, it is important to include in this list and note that finding the right group is key.

It’s much easier to remember numbers by associating them with memorable events.

Create meaningful groups that simplify the material. It takes a bit of time to conjure up a solid mental image. But the more you do it, the quicker it become Motivation.

It is hard to learn when you’re not into it. But if it’s something you’re really interested in, learning is easy

Taking responsibility for your own ,learning is one of the most important things you can do The big picture.

Structure your learning before you get started.Spend some time planning and identifying the key parts of your learning.

I have 4+ work exp in sap analytics domain.I have appeared this year gate but have not secured good enough rank and might get only lower NITs.I would like to appear again as I know I have good basics.Will it be too late for me to try again next year (5+ wk exprnc)? Ppl are actually asking me to try for MBA etc and saying that your work exprnc might be irrelevant after doing mtech.Is it true?I am actually trying for mtech to increase my analytics skills by learning machine learning and predictive analytics etc. so I think I am on right track.Please advise senior brothers because I am in lot of dilemma...I don't want to do some xyz certification or mba.I am financially stable and can invest 2 yrs in study.

When we were preparing for Gate this year, what resources did we have at our disposal?

Something like this :

Nptel

mit ocw

Gyanpal tests

GO tests

Free mock by coachings

Mock by iits

Prev year papers

Standard books(how can I forget that)

Stand alone video

GO chats

Testimonials outlining strategies by toppers

Other tests/things that I do not remember...

Now what about the situation after taking the exam.....

Something like this :

Some spreadsheets.

Pragy's app

A handful of posts by Mr Arjun and other contributors.

My point, pre gate material is abundant.

If you want to further contribute to community, share your post gate experience after things settle this year. I am talking about everything. Your journey to interview, accommodation, interview experience, ranks, competition, M Tech life, placements, time of results, date clashes, anything you can recall.

Because that stuff is really rare. This would help others, and since its rare, might make GO at top of search results most of the time.

Thanks. Hope I didn't waste your time.

I should not have done this but because someone is making such nonsense arguments I have to convey these.

Contributing to Open Source

As everyone knows GO is using Question2Answer software which is made for free and without any restriction by a great man Gideon. So, what GO has done in return can be seen here as plugins.

Ad revenue sharing

I just checked my Adsense account and I have got about 1600\$ so far over 2 years. Also about 10\$ per month from Amazon Ads. And this includes both gateoverflow.in and gatecse.in. And you can do the math for the expense about 30\$ per month for a server and we have 2. And for typing in previous year questions at GO I have to pay about 15\$ per 60 questions. Now anyone here can do the math and demand any share he/she deserves

Free education and charity

GO is free and unlike many free stuffs it is not made just for being free. It is made believing in quality. That is why we never provide short cuts or brainwashing students to follow bad ways just for our own benefit. What we do can clearly be seen here- I don't think it is charity and never claimed so also. But it surely does save students from sharks who even forces students who write genuine review about them to change it giving fake promises. I could have made GO ad-free but when we started GO, I was still doing my Ph.D. and even now I'm doing my Postdoc. These money are nothing for someone working in CS as you all know. This guy stooped too low by claiming the ad money is going to people paying US tax.

Idea of Q/A forum

GO idea was suggested by my friend Omesh Pandita. At that time we were answering questions on FB group and as time passes by they were getting lost. So, this was a good way to save them. As far as novelty of idea is concerned, we have started discussion forum way back in 2008 during B.Tech. and even for GATE many such things existed. Why GO is like this now is because of the execution.

Destroying GO

I was happy to close down GO and make the GO pdf available. In fact when the site had issues last year I almost did this. Then many aspirants messaged me saying they are missing GO and with the help of Pragy we restored the site. We only want to provide quality stuff freely to GATE aspirants. But since then GO has evolved a lot and is much more than just a Q/A forum as any genuine user here can see.

Copying contents

We admins add previous year questions here from GATE and other standard exams. Even when aspirants asked me to add "coaching institute" questions etc., I never did so -- not just because of copyright issue but also because of the quality issue. Still, people after giving test series add such questions here and hence I had to add a "Bad" button if ever a question is conveying wrong concept. Still, if anyone finds his/her questions here without permission they can ask for removal and those will be promptly and happily removed from the site as mentioned here.

 

When we were promoting genuine and world class videos for GATE CSE made by people like Shai Simonson, this guy started propaganda that they are not good for GATE and they should watch ONLY his videos. I have numerous aspirants who messaged me that they got tricked to buy his videos and now realize the stupidity. GATE stands for quality and one should learn from the best. If one goes for local stuffs, he/she can get local results. Those 27 toppers he claim - just ask how many of them paid for his course.

 

And if you want to know why this guy is doing this, can see this.

AIR 958(CS-Gen)

2)I have been called up for MS(R) at IIT Mandi on 14th May.ISI CAL has also written test on same day.Which should I choose?

And how good is CS in IIT Mandi?

Please Help!!

Hi everyone,

Its been a long time. I have been seeing a lot of complaints from admins/editors that they cannot contribute to GATE aspirants due to personal queries. So, I request everyone not to message or contact any admin here or in FB. All of them have their work and they are not doing a job here. If you disturb them they stop coming here and stop contributing. The following are the most common queries:

  1. How to prepare for GATE to get to top 100?
  2. I got this much rank - where can I get admit?
  3. Where should I join?

None of these are private queries and could be asked in public. Answering in public gets better results and also gets saved for future. This is the building principle of GATE Overflow and I hope everyone understands.

Those who are taking admission this time have found how tedious it is even after getting to top rank in GATE. This petition was made last year by Akash Kanase but was not proceeded with since petition for spot round was more important then. This time once admissions are over we can really push for this. I request you all to please provide data regarding the seat fillinf at IITs last year. 

IISc, IITB, IITK, IITKgp, IITM - all seats filled.

IITD - ? 

IITG/H/R - ?
