Hey Shubham!

Even if you have applied in the wrong course, you can still change your course and even College according to your eligibility percentage and criteria in the next cut off. You will just have to make sure that you are eligible for that course and the cut off percentage for that course in a particular college. To apply in the next cut off, you must before taking admission cancel your application from the previous college and course. Also, remember that in one cut off, you can apply only once. Also, in case you don't have to take admission in any DU college then you just have to cancel your application.

If you face any issues or still have queries, you may write in the comment section or you may also post your question.
