Hi Anupama,
Taking a drop and preparing for JEE can be good and cannot be. It depends upon the student that how he/she can prepare and whether will he/she be able to succeed in taking admission in any IIT or NIT with good percentile next year. If you think that you can bring percentile more than 93 that is approximately 94 to 95 then you must drop this year otherwise if you think that I will not be able to do then best thing is that you may take in any good private college or you can take the admissions in the state board government colleges. Best engineer and getting no college for which you are dropping then you must take admission now only.
I hope your question has been answered properly.
All the best for your future!
