Employ spaced repetition as part of active recall.

Spaced repetition is a simple and highly effective way to hack the brain. It forces learning to be effortful and, like your muscles, the brain responds to this stimulus by strengthening the connections between the nerve cells.

By spacing the intervals of learning out, you’re exercising the connections each time. Spaced repetition produces long-term, durable retention of knowledge. Studies show that repetition works best after four days.

1. Learn to use the active recall strategy.

2. Do this with the information you are studying in the morning, then again just before dinner.

3. Do this for a minimum of four days in a row.
