on the same page here, still revising stuff for jmss and yr 10 entry exam for nossal, i would recommend going to tuitions such as james an, since they do give similar exam formats and gives writing prompts where it doesn't actually sound ai generated, great practice if you are willing to go.
i would recommend watching jayce batallone's jmss guide video, as writing a checklist on the math and science topics stated (or for the ones you have not touched on yet) would be great.
this is coming from a friend who has done the jmss test last year, he said the science was about applying knowledge, not straight on science questions from what he could remember, and the math was not especially challenging, js work on efficiency and accuracy; do a lot of practice questions and exams, chatgpt may help.
i recommend timing yourself on practice tests / writing prac tests to really allow yourself to work under a timed condition so you can better prepare yourself for when the actual test comes.
i would probably say BBC Bitesized is absolutely amazing for the preparation, as it includes a range of topics that is included in the jmss test
