Is GATE preparation possible without coaching? Should I go for Classroom or Online coaching? Many more such questions float in the mind before starting GATE preparation.
Yes. GATE is possible without coaching and there is no compulsion to join any coaching. Many toppers every year prepare without any coaching. So, remove this bias from your mind that without coaching you cannot get a good rank.
Now if some aspirants are getting top ranks without coaching, should I also not attend any? Look. Every aspirant is different, every aspirant has different intelligence, different strengths, different situations, different scenarios. Even if we take two aspirants, who are COMPLETELY identical in everything but studying in different colleges, they will get different ranks because may be the college of one of them is more strict in attendance and assignments than the other. So, before taking any decision, think thoroughly. But if you think you have sufficient time in hand to cover theory in least time from your study material, you have good source to solve numerical, strategy to learn numerical solving skills, proper doubt resultion, etc. then there is no need to join any coaching.
Before starting to compare different ways to prepare, a brief introduction:
In self study, you prepare using standard reference books / notes. In online coaching, you prepare by watching Video Classes (Recorded / Live). In classroom coaching, you attend classes by visiting coaching centre.
