Hello aspirant,
If you want to take admission in college of engineering pune then your Jee mains score is of no use, you have to clear MHT-CET examination .
Moreover, If this is your Jee mains rank you can get admission in top nits, so you should definitely go for it.
Hope it helps.

Hello Yash!

3200 is a really good rank in JEE mains. I would suggest you to go for top 3 NITs rather than the college in pune. You might get computer science engineering in National Institute of technology, surathkal. If not, you will surely get computer science in NIT nagpur.
