I opted for a BSc in mathematics with computer science as one of the core subject. As the computer is highly demanded subject for placements. Faculties are not that good, some professors are good but some are very rude and doesn't even teach well. Fcaulty student ratio is very low. Almost around all faculty members have Phd degree so they all are very experienced. They teach well and clear doubt. But few teachers don't teach well so it depends on your luck which teacher you get. Semester exams take place in every six months, studying for semester exams is not difficult, study your class notes and do past 5-7 years paper whole heartedily and you will ace the exams. Yes but checking of the answer sheets is very strict so make sure you write well.
