JEE Main

No, there is no such exam. Moreover, IIT-JEE is only held only for central government run institutions across the nation.

You are not likely to get a government college in India. Hence, you'll need to get either into big private universities or into local engineering institutes. Check the best colleges in PUNE for Engineering or either apply for MANIPAL, VIT, AMITY, AMRITA or LPU for distance education. NIMMS also if you can afford.

No exact answer can be given as admission in SASTRA is on the combined basis of boards and Mains score.
Since you have a low boards percentage, you can only get into it if you have good Mains marks.
However, the branch is non-core, hence the competition will not be much.

With your Mains marks, you have no chances of getting any government. College throughout the INDIA for CSE (for general). Least are the chances at home state + local autonomous institutes. Check if there are any in your state or go for good private universities.

Sorry to say but you still have 0.6% less marks than required. Try if you can send it for reevaluation or if something can be done regarding that. Best of luck.

Seems quite difficult as 190 is not a high rank score. Although you should try for it anyway either in another college.

Moreover, at this rank you may get a rank it one of the decent NIT's. I would suggest you to check the cutoff of previous year for NIT's and then chose from.

Definitely not. Frankly, taking drop for JEE Mains is never a wise decision but is one for advance. Also, you won't be able to perform that well 2nd time which is though often seen. Go for good private universities and work hard their. That would actually worth your one year. Manipal, VIT, Amity, Amrita, KIIT and LPU are recommendations.
