I think you need to decide what you need the most...
Small group: Do you have a group of people who would like to do this with you? Some folks from your pre-med society, some pre-med friends? You will probably want them to be in a similar position as you as have less instruction with small group tutoring BUT you have more individualized attention and can focus on trouble spots rather than going over content and strategies that your group is more comfortable with. Ideal if you and your group are fairly motivated and can figure out your strengths and weaknesses.
Hyperlearning: For those that have a little trouble getting self motivated as frequent classes help keep that level of motivation higher. In addition, you get less specific but broader instruction on the content and strategies on the MCAT from 5 teachers. You can get some of that individualized instruction from your teachers during office hours. Be sure to use that time as it is part of the course (all too frequently, students don't take advantage of this part of our courses).
Both: You will get access to our online resources (practice problems, TPR diagnostics, and AAMC diagnostics, etc.) as well as our recently updated full color review books and our in class workbook and science and verbal workbooks - more than enough practice to keep you busy for the 3-4 months leading up to your exam date.
