Nobody will do this, there are only so many questions that can be asked.

Generally, a test like this will ask you to derive some result then to expand on it in several ways. I concur with other posters that the important part is how you set up the fictions you will rely on. If you get that wrong then all that follows is wrong, if you make a mistake you turn in many pages of garbage. I found one either achieves near 100% or abject failure, there is not much in between.

The thing is with very hard physics, when you are around people who understand you get the feeling you understand too, and maybe you do, but in the end there is a 1/r understanding potential around the people who really do understand.
