I apologize if this isn't the right section to be posting this, but I'm new to this forum. I'm preparing for the GRE and I've always had a good vocabulary, I'm not having huge trouble with the verbal part. However I have always been terrible at math, maybe I never applied myself or maybe it just never sparked my interest. Either way, I want to continue me education and I have to improve on this section. Right now I'm using the Princeton Review book to study, but they go a little quickly for my taste since I honestly haven't been doing algebra or anything close to it for about 10 years. Does anyone have a recommended method for studying if I really need to start from the basics? I was thinking about Magoosh but it's $80 just for the math part and I don't want to spend at if I get the same result. I think once I re-learn basics like algebra, square roots, etc. it will start to come back but I've been applying hours to studying and I'm not just getting it. Thanks for any advice.
