Since it is a take-home test, and you have 4 days to work on it, I am expecting you to clearly show all of the work that you did to get your final answer. An answer without supporting work will NEVER earn full credit, even if your answer is correct. YOU MUST SHOW YOUR WORK!
Also, please be honest about this. I dont mind, if you get stuck on something, if you get clarification from someone else, BUT make sure that the final answer that you submit (together with the work) is YOURS, AND YOURS ALONE! You will see similar questions on the final exam in just two weeks, so if you cheat on this test you will have won the battle, but I guarantee that you will lose the war
learn this stuff, and show me that YOU know it and understand it.
