I agree with Giovanni. It would be helpful to include something about the topic beyond which mock exam or book and your own counter.

Why would you want to do that? To interest people in viewing your post. They might either want to learn more about that topic or might already have some knowledge about that topic and be able to help you.

See UseAMeaningfulSubjectLine a JavaRanch FAQ.
