Hey Sakthi.

Getting seat in any engineering college mostly require the entrance test marks for providing u a btech course. If u are able to get admission in the good college then u can opt for the CSE , ECE , IT branches for ur placents and can get a huge package for ur job. But these branches are the top ones and u should be working hard to get and retain ur position there.

Hope u got my point. Ask if any query.

Good luck
