I know that a lot of my students are always worried about how and when to study. It is not so much the frequency it is what you are getting from the material.

If you are racing and racing through it, yet not remembering a thing that you read, whether it is our school material or even a spell book, chances are you are not studying properly. Why are you in such a hurry? Are you a race horse trying to get to that finish line?

The next time you are rushing and not remembering what you read think about this:

Reviewing a lesson a hundred times cannot be compared with reviewing it a hundred and one times.

- Rabbi Hillel,Talmud
