To clarify Huratio and RoadCone....
Correct.
Dependent on the subject, you will get either
(a) Class Participation
(b) You must attend 80% of tutorials OR YOU FAIL!
(c) A combination of A and B
OR
(d) No attendance or class participation requirements.
If class participation is awarded but no attendance rate is required, you should attend as many tuts as possible. It is easy to get a distinction plus grade in this component.
