Abhisehk, Mumbai University is considered to be top colleges among other universities of India. Mumbai University is ranked 34 in India University rankings. So, yes if you pursue your undergraduation from here, it will be definitely be worth. And talkinh about end semester examination, exam covers the topics from the course only. Topics which are only covered by the faculty are given in the exams , so if you give your attention to the topics during classes or after classes then its easy to crack the exams.

Thankyou!
