Here are some randomly generated multiple choice quizzes you can try. Pick the topic(s) you would like, the number of questions, and the level of difficulty. Hopefully you find this helpful. If you don't understand why something is marked wrong, shoot me an email or ask me in class. (Just tell me the code number of the question.) There is always the chance that I messed up, so please check with me if something doesn't make sense.
If you are interested in sending me some questions, please use this format for each question. Then send it to me via email, either as an attachment or in the email itself. You can put mulitiple questions in one file or email.
At some point, all the questions in these two quizzes will be in the database for the quiz generator above.
