Hello Bharat,

You didn't mention the exams name, so I would like you to tell some of the the exams for getting admission in BTech,

1. JEE main, JEE advance

2. BITSAT

3. VITEE

4. IPUCET

5. WBJEE

6. COMEDEK

and there are a lot many exams. You must know that IIT's are the top institutes for engineering in India, to get admission in those you'll have to appear for JEE main and if you clear the cutoff then you can apply for JEE advance and if you clear both of them then can apply for the college counseling. Colleges like NIT, IIIT and GFTI'S also provide admission on the basis of JEE mains marks. Bits Pilani is one of the best private engineering college of India, for this college you need to clear BITSAT.
