In online exams, generally questions will cover all areas of the assessing subject. So along with general score, also give topic wise score/percentage. If no question is asked from a topic, its % should be left blank. This is also a useful feature.

If the subject demands, you can give links in a corner pointing to external sites which are related to the exam subject so that people giving exam can refer those sites for information. But if the exams are very simple, then these doesn't make sense. So better have a provision to conduct exams in either way.
