Just curious, was there a general upward trend in scores? I submitted my first 7 graded essays on time, and got a 6/10 on every single one. The ones that I thought were really solid compared to the model, where the only comment was "good job," 6/10. The ones that were awful with comments like "this isn't correct at all, see the model answer", 6/10. Then on the very last one, returned today, I got an 8/10 with a note about how much I've improved, even though I know it was one of my weaker essays and I got two of the substantive issues completely backwards. I have no faith in the honesty of my grader.
The comments were pretty terse, things like "you writing could be much more concise, trying outlining more" (I don't outline at all), and "you got the rule wrong here, but good logical analysis so you still get points", but there was at least some comment and a grade for each sub-question, e.g. 2.5/4. I got 6's, 7's and one 8, which was also the last essay, along with an encouraging note something like "you do a good job of making things up when you don't know the rule".
I really don't think getting the rule backwards is that bad, or should lead to a low grade necessarily. For example, if you wrote a whole subsection about how under the FRCP the federal courts apply state procedural law and federal substantive law, you're obviously not going to get full credit. But if by doing that you show that you know the difference between the two, and that it's an important issue that the court needs to decide, the fact that you thought it was one way rather than the other isn't gonna prevent you from getting a decent grade (at least, that's what I've been lead to believe, and I honestly have to believe it otherwise only braniacs with total recall would pass the bar).
