My only concern would be a question of *retention*. It's easy to pass an exam if you're writing it almost immediately after taking in the information. But remembering the information at the end of the school year when you're writing your final exam and it's a topic you learned in the first week takes a different kind of study skill. It boils down to the old *Cram for midterms* question. How much do you retain? My take is that *retention* comes from revisiting a topic multiple times over the course of a year. One and done studying to pass an exam doesn't leave an imprint on the memory that's going to last.
