We actually got an 89% of on one of our tbl's.
We also always consistently score below average even though we still made As on the other ones. My group is more a blind leading the blind type of group instead of one of those groups where you have somebody who knows everything and is actually caught up. Also -- that last professor -- I wouldn't be surprised if she was a really picky grader. I think everyone can still fail the test, though, and pass.
You know, I really liked Benyajati's syllabus until about p. 100. After that, it just seems like a random collection of graphs and flow-charts without much explanation. The good news is that it seems from doing her practice tests that her questions aren't super tricky. At least we don't have Dormer anymore.
