Definitely in a better position coming back.

The material is easier to learn each time around, and it becomes more intuitive.

Also, there is a learning curve, of how to work problems, as well as another on how to effectively review. These things stay at or near where you left off.

Having been through four periods of intense study, I believe test-takers are better off with three periods of five weeks of intense study rather than fifteen weeks straight through.

It settles in a bit during the down time.
