1) Decide on a time limit if you are in a test. Don't go over the time limit or you might not have time to answer other questions. Depending on the time limit, don't go on a tangent when you have nothing better to say.
2) Annotate the source with everything you can think of. Even if something seems very obvious, write it down anyway. Don't go overboard trying to find clever things to talk about.
