<p>my suggestion for Physics practice book is absolutely KAPLAN.Every my friend uses Barron's and say it's a great book. but I found the part which explains you something about the physics is totally useless. But the Model test is fine, but it's much harder than Real SAT2s. In fact, Kaplan is very clearly structured and I really like Kaplan! Furthermore, my first language is not English, so Barron's detailed description of Physics makes me really sick. and Kaplan is very easy to understand. and it really talks about what is REALLY WILL APPEAR in REAL SAT2s!!!</p>
