This may be standard practice rather than any indication that the teacher felt there was a problem. </p>
<p>I would recommend that D (and maybe some other student in the course) visit the instructor and indicate that they did not feel the mid-term reflected the homework, so could he give some guidance as to what would be the best way to study for the final. I would avoid whining about the TA or the apparent disorganization of the instructor himself.</p>
<p>ETA: If you could post or pm a couple of examples of problems she got vs problems she bombed, maybe some of us could get a better idea where the problem is…</p>
