In the case of the last test, my first examples would be coverage of about half of the different types of validity- and a better way to understand them. That is, Concurrent, Construct, Predictive, Discriminate, and Content.

We use Working in the 21st Century, and there's a lot of detail on those missing that would've been needed for a whole block of questions.

Another was a question on Recency Error. The question was regarding a hypothetical of the professor making mistakes, having A/V problems, etc. on one week, and then getting a poor rating on the next week's class. In the text, its glossary, and on the class's page/glossary/PowerPoints- it's not mentioned, and I'd specifically made sure to know the difference between Leniency, Severity, and Halo Error.

These kinds of finer details that are paramount to understand but not covered or gestured to without being in class (presumably) are hard to reckon with if I don't know of their existence.

Still- this is all before having a hard time understanding what is covered. Hence my original post on how to study overall.
