I am reluctant to set up a marking system for assignments in which every little piece of a question is worth a quarter mark, and students have fractions of marks taken off for not dotting the i's and crossing the t's.

Instead, I have asked the TAs to award marks out of 5 to describe how well you have completed the assignment as a whole. The meanings of each mark are:

5: you have completed almost everything, and it is mostly correct; you seem to have a good understanding of the material.

4 : you have made good attempts at almost everything but with some non-trivial errors or omissions; your understanding of the material isn't quite as good as the previous category.

Most marks will be in the two previous categories.

3 : (used for two purposes)

      good, but you have only attempted about half the assignment;

      you have attempted almost everything, but there are quite a lot of errors or misunderstandings.

2, 1, 0: these will be only be used where very little has been attempted, or where most of what has been attempted is wrong. (I don't expect many of these, except 0's for non-submission.)
