IDON'TGIVEUP same I’m doing year10 entry too this year. Dont worry as edutest is conducting the exams, and they r generaly easier than ACER. however, that also means it’s a lot more competitive and also make sure to do a decent amount of extracurriculars, for eg, I’m in my school tennis, table tennis and badminton team while playing soccer for a club. Also volunteer anywhere , as that helps a lot too.
Personally, I only study for like 2.5 hours a day, as I did the test last year, and I know what to expect from the exam. Just don’t panic, anything is possible, just trust yourself and put in ur 100 percent, and u will be good.
