The AR Reading program that was popular in the early 2000s was an absolute disaster. It basically killed my love of reading for almost 10 years. They wouldn’t let me read books “above my level” based on some BS test that used timed reading. I wasn’t dumb, I just sub-vocalized when I read like a lot of people, so I read slowly. Read slow, don’t finish the test, grade poor, so “no books for you!” said the school.
If you have to ask someone else, then you probably won’t finish, and if you do, it will suck. Read some recently published papers, see what looks interesting to you, then check out the “future research” section that many of them will have.
