Lab test 1 - Sets, languages, countability, Turing machines, decidability, and undecidability

Go to this address and log on using the username and password that the demonstrator gives you. You will be presented with FOUR groups of 10 multiple choice questions. You must answer each question before proceeding to the next question. You will not be able to change your answer once you commit to it. If you get 8 from 10 correct, you advance a level. If you get 7 or less correct from 10, you stay at the same level. You will start at level 0. The goal is to reach level 4. Your mark will be based on what level you end up on at the end of 30 minutes, PLUS the overall percentage of questions you got correct, taking negative marking into account. Negative marking is calculated at the following ratio: the marks you gain from one correct answer is equal to the marks you lose for four incorrect answers.

Now, this multiple choice questioning system is in its first release, and the set of questions is incomplete. This means you may get the same question twice in one day (good for you) but it also means that there may be some problems with the operation of the system or with individual questions. If you think that the system is misinforming you about which is the correct answer to a particular question, please notify one of the demonstrators and they'll make a note of it.

If it turns out that that student has found a genuine bug in the system, they will be given a bonus of advancing one level from the level they are recorded as finishing on. However, if a student is responsible for three false alarms in a row, I'll start removing marks.
