Should I only do difficult quizzes?

No. Mixed difficulty gives better confidence and helps maintain momentum.

How often should I retake quizzes?

Weekly is a good baseline, with extra attempts before key exams.

Create high-quality quizzes that test understanding, not just memorization.

Start with a clear topic and level so quiz questions match your exam requirements.

Include a mix of easy, medium, and hard questions to reveal knowledge gaps.

Use explanations after each answer so every quiz attempt becomes a learning session.

Repeat quizzes weekly to measure progress objectively.

Focus revision on question types you consistently miss.
