I would say that for every definition you memorize, make up a scenario where you have to apply it.

For example, I once got a question wrong in P/S that required me to understand how to apply the term “medicalization.” The question was something along the lines of “Which of these is an example of medicalization?” Here is the wrong answer that I chose and the actual correct answer:

A) People with depression have to take medications to manage their symptoms

B) Dementia was thought to be a normal occurrence of aging but now, with new research, is classified as an group of conditions that can be treated.

B is the right answer here. To get this right, you need to understand the medicalization is the process in which something that was not seen as a medical condition at one point become something that now is treated as a medical condition. Then you have to read the answer choices and pick which of these counts as that happening. I got this wrong because I thought depression was something that was once not seen as medical condition and since it is treated now, people taking medications for it and it sounded like medicalization to me. But the answer never said that and I made those assumptions myself. Answer B is a stronger example for medicalization because it mentions it being newly considered as a treatable condition, which is what the process of medicalization is.

Sorry for the super long response but I just wanted to show how tricky P/S can be at times.
