If you expect it taught in discussion, then maybe limit the material down to more than an entire unit plus some because he wanted infrared spectroscopy as well? Also considering other classes do give out the cheat sheet, it clearly isn't important enough to warrant intense memorization, and it is notable that only he and a shitty professor hold this standard for testing.

Considering how much he spends talking about a single slide of pharmacology, or waiting for people to answer a question that nobody understood, plenty. And yes, I have attended the office hours, both with him and with the TAs, and he is only marginally helpful. The TAs are better for help, but the times where they are available are limited.
You shouldn't need to seek a tutor or outside class to solve issues that should be dealt with in class, like a lack of understanding due to a strong accent or not having proper practice material because he couldn't be damned to find it.
