My pace has me going ahead, but I just do it more or less in the order of the curriculum. I'll make an alteration in the order if I feel it'll suit me better. For example, we do all systems path second year. I felt that it would help me understand the physiology better if I did the path with certain systems that are less than straightforward for me (cardiovascular, respiratory, and renal).
I look at it like this; I have a finite amount of time to master this material. It's on me to do this, not the school. BnB, Wikipedia, UptoDate, textbooks, and practice questions have got me covered. School stuff is just a supplement.
Depending on the subject, by the time my school gets around to covering it, I would have gone through the material so many times, it'll be nothing to learn the extra stuff that they care about to be able to pass exams.
