Dear Aspirant,

I know this must be a horrific situation for you and my sympathies are with you but honestly, you need to prepare yourself for the worst. Don't get your hopes high. Be realistic and try to just qualify the examination so that you can take admission in a decent private colleges atleast.
Or you can try appearing for this exam next year with full preparation. Don't fear from these subjects , you are scared because you haven't tried much. Join a coaching institute (a good one) and start your preparation. Once your basics are cleared then only you will feel confident. Don't stress. Be realistic and face the challenges in your life. Everything is possible.
I am providing you a link which will provide you some preparation tips.

All the Best
