I want to learn paper 1 topics for my mocks in a single day. How do I do it?

I want to learn paper one topics in a single day but without the use of past papers if necessary for mocks this week. Does anyone have any tips (for any subject)? Thank you.

Most GCSEs contain two papers, so by targeting paper one you're targeting half the GCSE course. GCSEs are two-year courses, so you'd (roughly) cover half the course (one paper) each year. You're therefore trying to learn one years' worth of topics one day. That's an entirely unreasonable expectation, unfortunately.

Also, the fact that you've said you looking for tips on how to do this "for any subject" suggests that you plan to try this approach for every subject. It's just not going to happen. You need to put way more effort in than that. Sorry.

Nothing’s impossible though
