Dear Amba Sharma,

I would highly suggest you to please don't drop unless until you are very sure that you will work really hard to earn a good rank next year. Moreover, you can continue with your studies without dropping out an year and pursuing your coaching or self study for the entrance too along with it. This way you will save your year plus you will get another chance to secure a good rank too. Rest is your decision. Choose wisely.

Hope this helps.

All the Best!!
