When you learn during spaced sessions, you activate the same set of neurons repeatedly and that improves your recall over time.  German neurobiologists draw this surprising conclusion from their experimental studies with mice in mazes.

 

The classic thinking is that learning by cramming repeatedly activates the same brain circuits and facilitates retention.  Studies of frontal lobe electrical activity during maze learning showed just the opposite as neuron-firing patterns fluctuate more and retention reduces if the learning takes place without spaced sessions.  It turns out spacing such sessions with one hour intervals produced optimal retention.

 

Given this information and an impending exam, you might want to separate any repeated study sessions by at least an hour.
