I took TPR for each of my three times taking the MCAT. My first time I got a 7. Very disheartening. Well, the second time garnered me a 9. Still couldn't break the double digits. This was way back before TPR acquired Hyperlearning. Anyhoos, last year, I took the course and convinced myself I would break the impossible 10 barrier - not an easy task. I did every single passage that I could. I would read at a good clip, and highlight important points - after doing a bunch of passages, you start to weed through the chaff and see what is pertinent to the argument the author is presenting. When I got answers incorrect, rather than get pissy like I would in the past, I tried to understand why the MCAT answer was the "more correct" one. This was tough at first since the wrong answers still made sense. After some time (and still getting 7s and 8s on the practice tests) it got to the point (almost an epiphany) where I said "ohhhh, that's what the author wants, and that's what the MCAT question writers want."
When test time came around, I scanned through the first sentence or two of each passage, writing N(ow), M(iddle), L(ater) and K(iller) on the top of each (picking out the killer passage is key, as you need to do this one last. I then worked through the passages, reminding myself to stick to the technique I had learned. There was a lot of questioning going on in my mind during the exam, but I just stuck to my guns. Anyhoos, I got to the last passage and didn't even have time to read it - answered the questions I could get a feel for, or find quickly in the passage, then guessed on the last four. And I was mailed an 11 two months later. So, I suppose it is possible, because I never thought so til this happened. Good luck.
