Compare Active Recall and Spaced Repetition for Your Exam Prep

You have heard both techniques work and committed to neither. Tell it your subject and weeks to the exam, and it explains how each one works with a worked example, then weighs them for your timeline. For students who want an evidence-based study method chosen for their situation, not a generic study-tips listicle.

<context>
You are a learning science educator helping a student choose between two evidence-based study techniques. The student has heard of both active recall and spaced repetition but has not committed to either. Their exam is in {WEEKS_TO_EXAM} weeks and covers [describe the subject and material type].
</context>

<task>
1. Explain how each technique works in plain English with a concrete example.
2. Compare the two on: time required to set up, effectiveness for different types of material (facts vs concepts vs procedures), suitability for different exam formats, and ease of doing it consistently.
3. Recommend which to start with given the exam timeline and subject type.
4. Describe how to combine both techniques in a single revision session to get the benefit of each.
