CAT

It depends on what you have focused while pursuing your ECE. If you have been attentive in your classes and scoring well in your semester exams, then GATE will be easier for you. Most engineers find easy, and perform well in the quant section in CAT as well as GATE. English section is what gets the engineers struggling.

In CAT, to get admission in a top B-school, you must score above 70%. You might get interview call at lower percentage also provided you score amazingly well in your CAT. But, with a low score in your graduation, you must have an awesome profile to secure admission at a top B-school.

There are many non-IIT'ans who have scored 100 percentile in CAT. CAT is usually considered the forte of engineers, but many others also perform extremely well.

Your gap of a year will not at all be a reason of hindrance in your admission process or percentile for that matter.
