depends on subjects, but usually u would have too, but like for my subject today, Digital and analog systems, i didnt have to register anything at all, not even practicals...as i calculated there is 200 for lecture, but all the sessions for practicals caculated all together also are 200, hence there shouldnt be any extra anywayz, and most probz they check from the enrolments how many ppl there are enrolled, to how many ppl they can fit in a lecture....
just the thing im confused about, about my subject is
Lecture A: Tuesday 11:00 12:00
Lecture B: Tuesday 9:00 11:00
just doesnt make sense... A is before B.....but B's time is before A....
