Hello
Hope you are doing well,
You haven't mentioned which college and course you are asking about, so I will give you a very general idea about this. I also request you to please ask the question again in a clear way by mentioning the college and course so that we can help you better, generally in one year there are 2 exams, first the mid semesters which are usually of 50 marks and then the end semesters which are of 100 marks.
