HELLO,

With a 12 lakh rank in JEE Mains it is very difficult to get a seat in NITs, IIITs, or GFTIs especially for the OC category because:

• NITs and IIITs usually close around 2-4 lakh rank for the general category.

• for top branches like CSE, ECE, the closing rank is even lower often under 1 lakh.

• 12 lakh rank is quite far behind the usual cutoffs.
  
  But you still have options:

• Private engineering colleges :
  many private colleges accept students based on JEE Main rank or even without it.

  Recommended

• State counselling :
  Some state-level engineering colleges like in Tamil Nadu, Maharashtra conduct their own counselling and don not require JEE rank.

• Management quota- Private colleges also have management quota seats where rank does not matter much but the fees will be higher.

• Diploma to degree
  another option is to do a diploma first and enter engineering in the 2nd year later.
