Space and mix your practice
Read & notice
Instead of repeating one page many times at once, revisit it on different days. This site uses a simple review schedule with intervals such as 1, 3, 7 and 14 days as remembered cards advance. It prioritizes mistakes and usually limits a review session to six cards.
Spacing and retrieval are supported as general learning principles. These particular intervals are a design choice, not a proven optimal schedule. Mix letter recognition, meaning and sentence use, and return sooner when something is difficult.
