I think over the next month that message will be changing a little, but it will always be what is best for our students. It may seem surprising (which is kind of a sad statement about the prep industry in general) that someone says you don't have to spend money when they can profit from saying you should, but BR has been doing MCAT longer than anyone except Kaplan and an honest, sincere approach to everything has worked so far. No reason to change that philosophy now. It's a company run by teachers.
However, like I said, the message will be changing little. First off, after hearing back from several students following their recent MCATs, our NEW organic chemistry books are the most important books of any kind anywhere (more helpful than every source you could find). The first book is a conceptual review of organic chemistry and the second book is heavy of biology and biochemistry examples. The feedback has been overwhelmingly favorable at how useful the passages were and how insightful the tricks and strategies have been. So given the recent and repetitive feedback, we feel you should invest time in our newest organic chemistry books (over our older ones and especially over other sources). Organic chemistry and it's analytical approach, is key on the new MCAT and that is what our books do better than anyone.
Our new physics books are finally printed and ready to go. They have several new passages and more biological applications. The same is true for the general chemistry books. If you can afford to get the new ones, you definitely should. If money is tight, then working from the old ones and omitting material that was removed in 2015 will work too.
