I'm veryyyyy late to this but honestly
Your marks, since you're a ruse kid (no offence), probably aren't the most accurate representation of how you would perform in a maths HSC
And it's hard to know where you sit compared to the rest of the state in Year 10
Firstly ik this wasn't ur initial question but I would still try to do at least adv math in your situation, 60% isn't terrible, I don't know exacts but I'm 90% sure there are ppl in my school take adv from not great marks (and I don't go to a top 5 school either so)
I also assume your current study schedule isn't what it would be in year 11 and 12, so there's always the chance that you just need the time and effort - and maybe a change in content (I know that if I took standard, I wouldn't understand half of what's happening - like what on earth is a network my friend tried to explain it to me)
And worst comes to worst you can just drop in year 12 yippee
Anyways, about tutoring
I would recommend seeing if you have any friends in older grades and if they'd be willing to help you at like lunchtimes or smth (or pay somebody who's graduated)
They're more likely to understand your school culture, the way your teachers teach in case something confused you, and also having a friend help is just better than some rando imo
Tutoring also doesn't work for everyone - there are plenty of kids who do well in my school w/ tutoring but also just as many who do well without, I would recommend private over group bc group just makes ppl learn content earlier (from what I've heard) whereas 1 on 1 can help you directly with specific topics
And my final advice, when ur studying
Don't hyperfixate on super hard questions - dropping those marks is better than dropping easy ones bc those questions are designed for maths genius if ykwim
Try and solidify the basics and remove any and all silly mistakes by slowly but surely practicing
Idk if this exists for year 10 but like I would look at the prospective band range for a question - if somebody is low band 5, imo its better for them to focus on getting all the band 5 qs right instead of a band 6 one here and there
Oh and attempt every question!! Just writing a formula could get you a sneaky mark
Anyways my year 10 environment was super diff so hopefully some of that was relevant
You can do this!
