In the study comparing intensive and spaced learning of math problems, one group solved the problems in a single day, while the other group spread their practice over three days, each a week apart. Four weeks later, both groups were tested on new problems from the same topics. The spaced practice group scored twice as high as the group that crammed.

This video presents four scientifically-backed study strategies to improve learning and two ineffective strategies to avoid (highlighting and rereading). The video aims to help viewers become top students in any subject by implementing these techniques.
The video explains that spaced practice, also called distributed learning, involves spreading out learning sessions over time. The longer you want to remember something, the greater the spacing interval should be between study sessions. For example, to remember something for a week, sessions should be 12-24 hours apart; for 5 years, they should be 6-12 months apart. The timing of practice significantly impacts learning outcomes, with spaced sessions producing far better results than concentrated sessions over a shorter period. This is referred to as the spacing effect.
