The table shows your grades for the Professional Issues essay. The requirement is for a pass/fail but I have graded them 'A', 'B', 'C' for your information. 'B' means you produced something average. 'A' meant it looked as if you had made an effort, brought in additional material or argued your points well. 'C' meant there was a problem of some sort. An 'x' means that you were in the database but not on the mark table I was given so I assume you weren't expected to produce anything. A '-' means I've not seen anything from you and you should have had mail asking why. (lost e-mail or non-submission) Four of you submitted material good enough that I reckoned it was worth commenting on so you got an "A*".
No-one submitted material so bad I felt I had to fail it so if you submitted something you passed.
I didn't write much on your individual submissions but you got marked down for things like only referring to one talk (I wanted some indication you had been to a few of them), lack of structure (big slabs of text with no paragraphs or indications that you were doing more than just dumping words on the page), being way too short, wandering off the topic, failing to come to some sort of conclusion at the end. There is inevitably a little random noise on the grades - marking essays is always subjective.
I marked you up for the reverse of the above and for developing a clear argument, using references, effort, readability and so on.
