After you finish a "bar course," commit to re-learning the material frequently while you are still in law school.
The Forgetting Curve
Hermann Ebbinghaus (1850-1909)
Ebbinghaus' research discoveries include the Learning Curve and the Forgetting Curve. Most people are familiar with the Learning Curve, but not with the Forgetting Curve. (Perhaps they forgot about it.)
His memory experiments demonstrated that
meaningless information is more difficult to memorize than meaningful or information that is relevant to the learner;
increasing the amount of material to be learned increases the amount of time it takes to learn it (learning curve);
relearning is easier than initial learning;
it takes longer to forget material after each subsequent re-learning;
learning is more effective when it is spaced out over time rather than crammed into a single marathon study session (spacing effect); and
forgetting happens most rapidly right after learning and slows down over time (forgetting curve).
