Your category rank is 20190 and Rank in CRL is around 3 lakhs. With this rank, it might be difficult to get any good NITs or IIITs or CFTIs. If you have home state quota in any of these NITs or CFTIs you can expect a seat there- North East NITs, NIT Hamirpur, Assam University etc. Coming to IIITs, the SC seats gets filled within 10000 rank almost. In your previous queries, you told you belong to Uttar Pradesh. Now SC Seats in IIIT Allahabad usually filled within 4000 to 5000 rank. However this is based on previous few years' data, and this year it might change. You may go for private universities such as Galgotia, Benette or Amity University etc. Check the cutoffs here http://engineering.careers360.com/articles/jee-main-cutoff-for-top-iiits
