I did the ANIT flashcards that I found on quizlet, which helped a decent bit, but I would HIGHLY suggest finding as much ANIT info that you can. There were many questions that I had not seen before on that portion, but since I am interested in the subject, I happened to know many of them.
I used my notes from college to study math and science portions; as a recently graduated aerospace engineer, these subjects were quite fresh for me.
I'm not sure how to study for reading TBH.
And lastly, I did a lot of Jantzen simulator, basically 1 hour per day for 2 weeks. The key with this, in my opinion, is to focus less on the score and focus on the feeling. Try to get to the point where if one of the targets change directions, you don't panic and go the wrong way.
