what is unit 1 over?

we have our unit 1 test tomorrow and our teacher unlocked the practice checks and its like nothing we went over. they mention things like thermal pollution and CAFOs but we were learning about biomagnification/accumulation, endocrine disruptors, POPs (which are sometimes mentioned) and pollution (ie, nonpoint/point, also sometimes mentioned). is our teacher going out of order or did i just not pay attention lol
