B.Tech Electrical and Communications Engineering

He should focus on basics and practice more and more.
Before clearing an entrance exam all the branches have same criteria.
It may vary college to college due to their facility and infrastructure.
If he wants to join ece just tell him to focus on practice and fallow what teacher is saying in his classes.
That will be sufficient no need to worry.
In case if will not get ece he can change his branch to ece after end of first semester.
Because first year in engineering have common subjects.
Here is a link of exams. I hope it will help you.
Thank you.

B.Tech (EE) placements are above average and for ingenuity, we have a separate placement cell in which proper monitoring on every student. If we talk about the students who lost their jobs after an interval, it depends on their skill and learning growth, if you have different ideas and thoughts for the growth of the company then you can survive in the market, otherwise, with the same skill and no add-on in learning capacity, you will stick to the point which will not give you the growth and may get you terminated from the company.
