Helo gunarsee, your jee percentile is 52 and is not good at all. I would suggest you to use this link for predicting the rank.

Also i would suggest you to give the exam again with full motivation and dedication and prepare for it only through NCERT pattern and suggest you to not take the route of competitive books.

I hope this helps. ALL THE BEST.

Hey aspirant, your Jee main percentile is really low. At this percentile, your expected rank is about 4 lakhs which is low enough to expect any college because from the assumed cutoff of 70 percentile you haven't even cleared the cutoff.

I suggest you must focus on your studies more and try to improve your percentile in the April paper of Jee mains.

Hope you will understand and try to give your best.

All the best.
