How to memorise gcse markshemeWatch
Questions are also random between exams so there is no chance that you'll find anything that is worth it within the exam you take, within the other exam boards.
All in all, while the way to memorize an exam board's mark scheme is simply to re-read it or try and do memory tests and the like with it (Can't really "apply knowledge" to an exam answer thats already been answered), your best bet would be to learn the content of the course well. Things like:
Testing your memory with revision cards
Teaching the subject to another person
Doing exam questions or papers
Making something fun relating to remembering it (For example, my school uses questionable phrases to remember some equations)
These are all much better things to do instead of memorising an exam board's mark scheme for a paper, seeing as if you do learn the content, you won't have to worry about making mistakes again.
Hope this helps.
