There is no relation between made easy CBT and gate exam. gate never asks aptitude of such level and gate never gives the question like finding candidate keys of (A,B,C,D,E,F) with 8 relations in 1 mark.
Just be confident and don't compare yourself with toppers. Focus on yourself.All the best.
today I was giving advance level 8 of made easy and in that topper score is 99/100 and he has taken 1hr 5 min to complete it and in some questions he has taken 0 second to attempt question and they are correct. So if you compare yourself with made easy toppers you will never gain any confidence and only doubt yourself.
