You will have 2 semesters wise in a year and 5 subjects two labs and 1 open elective.. open elective is something you need to choose a subject at the beggining of the semester and you need to attend the class once or twice a week.. some electives don't have exams..instead activities.. but some have.. you need to clear that to clear your semester.. but this won't add to your overall percentage.. it is just for your clearance of the semester . Faculties are very cooperative.. they will teach you the major syllabus but the portion which they don't teach will be in exam paper .haha.. I suggest you to please don't waste time roaming around the college.. after the college hours..the staff will be free.. go and clarify your doubts..
