Dosanjh is cooking (ˉ▽ ̄~) 🔥 u have pretty good chances but remember the maths DOES NOT exceed the y8 curriculum, i cannot put enough stress on this. you need good problem solving and critical thinking skills to do well in the maths aspect, not simply knowing topics well above your year level. i was also doing year 10-11 maths around this time (logarithms, non right angle trig, etc) thinking it would help but literally all that came out was probability, algebra and geometry. im not saying stop doing accelerated maths, by all means u should continue it to stay ahead, just dont expect it to pop up on the exam. as for english year 8 level is perfectly fine, just make sure your vocab is good, read a ton of books and practise writing and u should be able to get in easily
