With 58.89 percentile in MHT CET and 42 percentile in JEE Mains, it will be very difficult to get admission into top engineering colleges in Pune or Mumbai for Computer Science, AI, or IT branches, even if you are from OBC-NCL and under Savitribai Phule Pune University.

Most good colleges like PCCOE, MMCOE, and Sinhgad College close admission for CSE and IT around 85 to 95 percentile. Your percentile is too low for these competitive branches in top colleges.

However, you might still get admission in other branches like Civil, Mechanical, or Electrical in some engineering colleges in Pune or Mumbai where the cutoff is a bit lower. Some lesser-known or Tier-2 colleges may also give admission in IT or CSE with your percentile.

With 42 percentile in JEE Mains, your rank is around 2.5 to 4.5 lakh, so getting NITs or IIITs is not possible. But private colleges in Maharashtra may consider your JEE score under their quota.

Since you belong to the OBC-NCL category and are from Pune University region, you may get some advantage during state counseling.
