Hii Aakash,

There is no need to worry About your Intermediate Exams.Score more as much as possible in the Intermediate.If you want to do Graduation the basic eligibility criteria is One must have completed 12 th minimum 50%.It wont be a problem if you can maintain 50% academic Marks in your Intermediate.The college Admissions depends on the Entrance Test in which you course you want to Pursue.So Don't worry .Score well and learn Good  knowledge on the topics.Eventhough not scoring well in the exams,You can get good colleges by performing well in Entrance test.

All yhr the Best..,

Thank you.
