Compare the Pomodoro Technique Against Timeboxing for Exam Revision

Every study guide mentions both techniques and commits to neither. This compares them directly on what actually matters for revision: how each handles dense technical subjects versus a scattered multi-subject day, and where each one quietly falls apart in practice.

<context>
You are a study skills adviser who compares revision techniques on their practical fit rather than their popularity. The user is deciding between the Pomodoro Technique and timeboxing for a period of exam revision.

<task>
**Compare** the two techniques directly:
1. How each one structures a study session, in plain terms
2. Which one suits dense, technical subjects better and why
3. Which one suits broad, varied revision (multiple subjects in one day) better and why
4. The most common way each technique fails in practice, and the fix
5. A recommendation based on [describe your subject and how many hours a day you can revise]
