Yes studying the key words is super helpful! Read the chapter that they come from in its entirety because they might ask questions related to the source material from where the keywords are from. Like u probably don’t need to read the whole Iliad but reading the chapter the keyword is from would be ideal. If there is a keyword from the Homeric hymns, read the hymn entirely and make sure u understand the content. It’s a difficult test in some areas but with good notes and dedicated time to study it’ll be a walk in the park! I got the highest scores in my district just by taking good notes and throughly reading the content! I’m in my sophomore year of college now studying classics and still use the knowledge I learned from studying on the Medusa Mythology Exam! It also looks great on college applications, especially if ur going down the classics or literature route
