Making notes

Does making notes in the sense of reading textbooks and school work and combining them into notes instead of copying count as revision

Yes because you’re revisiting content. But, this is very inefficient. I’d suggest turning notes into flashcards so you can review it frequently.

In the most general sense, yes it counts as revision. You are reviewing the material and writing it in your own words, which is hugely important for verifying that you understand the material.

However I feel like there's some underlying question here. Perhaps you're trying to justify to yourself that you've done revision? Or that you're trying to do X amount of hours of revision? If that's the case, I'd recommend not looking at revision in that way. What's important is not the amount of hours or the method, but that what you are doing is helping. Some people will tell you not to write notes. I personally got top grades throughout my GCSEs, A Levels and degree with little more than taking notes and past paper revision. None of that matters though, what matters is if the method works personally for you.

So in that sense, it counts as revision if you're getting value out of it. While it's a time consuming process, there is a lot of benefit to having notes written in your own words, and to generally have a "one stop shop" for everything you need to know. If you're not finding it valuable though, you'll need to supplement it with other types of revision that work for you. That could be flashcards, mind maps, audio that you can listen to, and so on. What matters is getting results, and that's what really makes something revision.

@acsel my reasoning is I’ve started revising for my mocks in January and allowed 9 weeks for it, but this includes a week of note taking so unsure whether it’s 9 weeks of revision or just 8 and one week notes, as my revision I’m was 9 weeks and don’t want to cheat myself
