This site is designed for individual GCSE and A-level science students who want a clear, structured way to revise — without jumping randomly between topics.

You don’t need to watch everything.
You don’t need to start at the beginning.

How to use the site

​

Step 1 — Identify weak topics
Spend 10–15 minutes identifying which topics you are weakest on.
If a topic feels uncomfortable or vague, mark it red.

Step 2 — Work through weak topics only
Watch the videos for red topics and make brief notes.
Don’t move on until the explanation makes sense.

Step 3 — Check progress regularly
Re-mark topics from red → amber → green.
Most students finish weak topics within 4–6 weeks.
