Hi! I'm a newcomer to this forum and I am also sitting the JMSS test this Saturday 
Hopefully it's not too late to be a part of this conversation and to exchange knowledge with one another 
nah mate, its all good. Basically, most of us know our year 9 science and maths textbooks well. Most of us also have gone into further detail within the 2 subjects as well. Me personally, have gone through year 7,8, and 9 (and year 10 chemistry) Science and made short, dot point chapter summaries to look at on Friday.

For maths, I have gone through year 9 curriculum and year 10 basics. I have done 5 ICAS Science exams to prepare me as well as practise essays on various topics. I have attended JAC and Hendersons. JAC was not good, I think I only obtained science writing and timing skills from it. Hendersons were good, but likely nothing you didn't already know. They gave some shortcuts and so to help speed up my confidence and timing. If you did Mhs, nhs, schs or macrob last year, the maths and numerical are very similiar! Good Luck to you and I have been advised to not study on Friday (just read over notes).
