Hi Aspirant! Different courses have different fee structure. Kindly specify which course are you interested in. And if we talk about semester, then a whole course is divided into semesters. Usually, one semester is of four working months. Generally, a 3-year course has 6 semesters. Also, different subjects are taught in different semester. Moreover, exams are conducted every twice a semester i.e. mid term and end term exam.  

I hope this information has helped you!
