Hi aspirant

You have scored very less .Its better to prepare for the next year.You are not clear with the concepts which you have studied in your intermediate.

So you should take a drop and study well.

Even if you take admission in any private college(You are not going to get government college), you will fail from the first semester.

You have to study the same physics,chemistry and maths (even tough than 12th) in your 1st semester.

So don't put yourself into problems.Prepare for the next year.

Its very difficult for you to get any decent college with 46%ile in JEE mains.

hope this was helpful.
