I am in 3rd year of my B.E. Degree in civil engineering. I am confused weather I should join coaching classes or prepare myself for GATE.
You must join a coaching class for preparing for the GATE for the following reasons:
1. Classroom coaching offers one-to-one access to ace professors in the industry, which online videos do not offer.
2. Peer group: almost all of the students taking this program are serious about their studies and hence, you're benefitted and motivated in a classroom structure.
3. Tests : with periodic tests, a good class benefits you to always improvise on your score.
If you're from Mumbai, I can suggest to you some good coaching classes and then you can choose amongst them and decide.
