Participating in quizzes or flashcard reviews reinforces knowledge through active recall. Setting goals for reading and digesting materials within specific time frames can keep motivation high. Additionally, teaching concepts to others can solidify understanding, while utilizing multimedia sources like videos or podcasts offers varied perspectives to enrich the learning experience and deepen engagement with the subject matter.
