DSE MistakeBook

Turn wrong answers into marks on the next exam. Mistake Book is a private mistake journal for students. Photograph a question you got wrong, review it before you forget, and quiz yourself on your own errors — so the same slip does not cost you again. HOW IT HELPS YOU SCORE Exams reward what you can still recall under pressure. Logging every mistake, then coming back on a schedule, is one of the most reliable ways to raise your result. Mistake Book follows the forgetting curve (1, 3, 7, and 14 days) so you revise while the memory is still there to save.
