Hey are you following a routine for practicing and what material are you using ?
I have a pretty solid routine. I am a Masters student and am currently doing research and TAing a structural biochem course. My routine is this:
1. Get to school everyday at 7:30 m-f
2. Tu/Th I show up to the class I am lecturing at 8am and stay until it ends at 9:20. On M/W/F I start studying at 8am and usually review the latest practice exam I took going over everything. on Tu/Th I do this after lecture at 9:30am. I will do this until about noon everyday.
3. I work in lab for 3-4 hours everyday depending on how much work I need to do.
4. Study again anywhere from 3-7pm or 4-7pm. I continue to review the latest practice exam until it is finished.
5. I spend 2-3 days thoroughly reviewing these exams. I read every question based on subject, not on order. For example, the physical sciences are broken down to physics and chemistry. I will start with physics and look at my percentage correct. I may have gotten 4/5 questions right on the topic of "light and geometrical optics." I will review the passage and the questions again to see where I went right/wrong. If needed I will go back to the books and re-review.
6. When I am finished reviewing the old exams I work on my EK 1001 questions for every subject. I will do every subject in the book but every 4 questions so I am hitting all the topics. For example I will go through general Chemistry questions 1, 5, 9, 14 etc. until I have finished the chapter on which I need the most work in. I determine what I need most work on by reviewing my statistical analysis provided by the AAMC practice exams on e-mcat.com. Each practice exam costs $30.
7. I study about 5-6 hours a day for 5-6 days a week
I use only the EK books and love them. I studied MCAT last year but never took the exam because my scores weren't getting any higher than 34-35. 3 weeks before the exam I was getting low 30's and got discouraged. I studied using Kaplan books the firs time through. They were ok but they definitely provided way more than needed. EK tells you what equations you absolutely need to know for the MCAT and having gone through practice exams I haven't needed an equation they said you wouldn't be required to learn. What also helped me is that I found a small study group here on SDN. I just asked the forums if there were any students in my area that wanted to get together to study and have company. 3 of us study together regularly and we just sit and study with the occasional questions based on topics were learning. It's much more motivating having peers studying for the same thing and it pushes us to stay and work longer. More than what I would have done if alone. I have 2 1/2 months to take the exam and feel pretty good.
