Go for berkley review, its intense but worth it. I took it as well as Princeton Review. I would say it also depends on what ur weaknesses are and ur strengths. Princeton is good for biology and also general chemistry. I personally didn't like Berkley Review biology. It was way too dense. Berkley review teaches you a lot of trick for gen chem, which I was so grateful for. Berkley review gives u very good and difficult practice exam, so no matter how hard ur exam is, you'll always be prepared due to the level of difficulty that Berkley review exam gives. If u have any questions, send me a private message.
