hello abhishek

I hope you are doing good. Firstly I  want you to know that nothing can be achieved without self confidence if you only think that you cant crack the exams then definately you will never able to crack it. To be practical exams like SBI entrance are very very tough because no. of appearing is quite high but if everyone will think the same way you are thinking , then noone will crack the enrtrance. You just need to join  a proper coaching with a proper roadmap and give your best with consistency with 8-9 hours and try to cover easy topics first and never feel depressed . You will definately land somewhere in good position

Hope you found this answer helpful. Good luck for your future
