James Ann is generally pretty solid, but in my opinion doing the Edutest Samples helped me a lot for getting into JMSS. If you are looking to purchase the test packs I suggest getting the yr10 and yr9 packs. Now, Edutest sample will mainly cover your math prep, but if you do notice if you have any weak points you might want to practice more. In addition you can find plenty of practice questions for math online (free/paid). Now the scores you should be getting should be at 18+/20 and you should be able to finish them in at most 12mins. As for science prep, I suggest revising the yr7-9/10 Science curriculum and doing ICAS science as a practice exam as it gives you a good opportunity to practice your skills.
