hello aspirant,

I would like to tell you that you will get your branch in B.Tech according to the rank and cutoff marks you will score in JEE mains and JEE advance.

Further,I would like to tell you that Engineering / Technology / Architecture / Science / Commerce / Arts is eligible to appear for GATE 2022 examination. Those who have completed section A or equivalent of such professional courses are also eligible. There is no age limit criterion defined by the exam conducting authority to appear in GATE.

Also, if you talk about which is the best Engineering branch to give GATE Exam, then the answer is Electrical or mechanical are the best branches for GATE. But that doesn't mean that CSE or any other Stream student cannot give GATE Exam. any B. tech graduate from any stream can write the gate in any streams offered .

Mechanical engineers ,Electrical engineers and chemical engineers with good GATE score is mostly preferred by PSUs .

I hope that this will help.
