Start with the theory, getting you to draw diagrams etc. I'd prefer this on a google meet or zoom. From my general experience, you can move onto a new topic or section once you can get five or so questions right in one go. Those range from definitions (always catch people out) up to higher mark questions. Memorizing equations is also very useful. I'd offer the option to derive these too - that highly improves your mathematical understanding of where the equation comes from and what it is related too. In my honest opinion, understanding a physics subject is being able to combine both the maths and theory together.
