I've seen TPR FLs ranked pretty low around here (most notably in SN2ed's posts, which cite a large variation in opinions as the reason for the low ranking), but my TPR scores were quite close to my AAMC scores (0-3 points total score difference, and if I remember correctly, not more than a 1 point difference on any individual section.) Granted, I only did a few of the TPRs and a few of the AAMCs, so that may not be a useful comparison. With respect to the verbal section though, I have to say that I definitely found TPR to be very representative of MCAT verbal. I'm interested to see what others have to say, since I myself am debating between the TPR CBTs (the ones I haven't done yet) and BR CBTs, given the general consensus that the BR science sections are generally harder than the real thing (the trade off being the verbal section.)
