The client tested several approaches. As a result, a scientifically based method of memorizing information using special cards through interval repetitions was chosen. According to research, an hour after reading we forget 50% of the information, and after 10 hours about 35% remains in memory. Regular repetition of material helps it become embedded in long-term memory. Depending on the degree of memorization, the interval between repetitions changes. This method involves breaking a large amount of information into short and easy-to-remember segments.
