Universities in India have two admission semesters- Spring & autumn.

Government universities in India have different admission criteria. Like they take different exams like JEE Mains for admission and give results according to the performance of the candidate. If you clear the exam only then you will get admission in the respective course.

In private universities, you can also join in between the semesters by giving a particular reason for the delay without scholarships.
