I heard Kaplan practice tests are easier than the subject tests. I’ve been getting low 700s with the kaplan physics sat practice book, but I’m not sure if that’s actually representative of what I would actually get. Does anyone know if it’s a good prep book to use? I’ve been trying to learn some physics 2 material (I’m in ap physics 1 right now) with it, and I hope everything they cover is sufficient for the test.
