you all should know what subjects you all will be taking, then
go and study. no point wasting your time to study blindly.
also, poly does not seems that slack as it seems.
you can play and slack and skip lectures etc.. no body's business,
since you are paying the fees to feed the lecturers.
also, if u are those who aim for a D grade (50-55%) then the slack
attitude. for the A+ people, then must study..
of course, need to have interest in the subjects, and non-bias
teachers.
and finally, its not easy to get an A, nor easy to Fail, but we
need average 75% (GPA >3.5) then can go uni.
