This falls under the category of "Doing your homework for you". In the time that it took you to type out that post, wouldn't it have been easier just to use your knowledge and answer the questions on your own? At any rate, if you don't know the answers to some of those questions, then you need to study for the exam anyways, which defeats the purpose of getting other people to answer these review questions...

(I assume that by "exam questions" you mean "exam review questions"...)

Those exam review questions are there for a reason. Mabye, you know, to learn the answers so you pass the exam. So, how about you review for them!!!
