First, be sure to use the Official AAMC materials. No matter your budget, this is something you need to purchase and use. The practice tests are going to be the closest to the real MCAT. After all, its the same creators. As for which MCAT test prep company to use, I used Princeton Review and I was very happy with my experience. The reason I am a proponent of the Princeton Review is that they over-prepare you (but not excessively so), thus helping you achieve a top score. Verbal is a tricky beast that requires constant practice, in contrast to the other subject areas. A classic favorite is the EK 101 (ExamKrackers) verbal passage book which is fairly representative of the real exam.
Check out Part 2 for a study schedule on how to actually implement these resources in the months leading up to your exam.
