What are people's thoughts on the Kaplan classes? I have a number of books to review (OG, Kaplan 800, Kaplan premier, etc) for my study plan. I was going to do a self-study from the books in my attempt to approve on my 700 from last summer. I got a 44Q/41V the first time and I'm really trying to bring up the quant score to offset a low GPA. I only reviewed one book and took a few practice tests before the first exam so I think that some strong self-study might be enough. But I sat in on the free Kaplan online class this evening and they had some really good hints/tips I'm not sure I would have picked up just studying from the books. They have the On-Demand version which is only $400 but I'm not sure if it is worth the cost or not.
