Yes, both B.E. and B.Tech Candidate can apply for GATE exam as there is no difference between BE and B.Tech degree just a different name for engineering degree.

GATE exam can be given after B.Tech. Based on your GATE score, you will be given colleges for pursuing your M.Tech and it will also help you in getting better jobs.

No, it is not necessary, but GATE is an important exam to improve our skill, and I think GATE is compulsory for graduation. And it helps you in achieve good rank in PSU under direct basis of GATE and you are eligible to get job.

You must join a coaching institute for GATE 2018 batch. You must take a crash course. You can also join the test series for GATE exam in 2018 batch. Better to join Made Easy coaching.
