JEE Main

Hi Ganesh,
Most colleges have a provision for management quota. You need to contact the institute officials personally for specific admission details as it differs from one college to another.
Hope this information helps. Please feel free to revert.
Wish you luck.

Hi Himanshu. MNNIT considers students on account of JEE score. It is one of the very good institutes.
Now coming to non-JEE colleges, you have Bits, indraprastha university, Vellore, Manipal, srm and such good colleges that dont consider JEE score but take their own respective entrance tests. These colleges have best teaching faculties as well. I would not recommend dropping a year. Instead prepare for these. All the best!
