frick that qn it was a careless error, if ur gonna help , help me w b) ii here. I was able to take out the inverse pre easily, but they somehow found dy/dx before even finding the inverse? I tried taking the inv c(x) to the lhs but even taking implicit diff I came back to the same friggin eq

Hey, everyone :).
I‘m scared for maths ext 1 next year. If anyone has completed prelim, is it hard 😅?
FYI, I was in 5.3 maths this year but I failed two of the assessments and barely scraped by in passing the course overall.😬 (I ended up with B7 on my RoSA, which I’m pretty sure is kinda bad if you’re in 5.3).
I tried really hard in my study towards the assessments but during assessments my mind shuts off and I forget EVERYTHING istg.
Does anyone have any tips on how to combat test anxiety, along with addressing careless errors.

Sidenote, I am aiming for a 99+ ATAR and getting into med school to become a GP (I know it’s very ambitious and very unachievable) along with getting all - rounder in HSC. I am willing to put the work into achieving this. My family is not in the financial position to afford tutoring so I will need to work hard.

In summary, is it possible to have an ‘academic glow-up’ such that I achieve a 99+ ATAR, or am I just delusional and in denial and what should I do over the holidays to prepare?🤡

I wish everyone the best of luck and pray for your successes going into prelims next year!

P.s - Sorry for my very unorganised writing (my brain ain’t functioning after my traumatic y10 yearlies 💀
P.s 2 - I’m planning on taking 4u.

OH ur thinking 4u, nah dude this a 3u paper- r we allowed to use 4u methods for 3u tests or ?
it's not in 4u i just saw the formulae and thought they were sinh and cosh
also cosh was in the 3u sample paper (the catenary)
yeah u can use 4u methods i think just don't get the wrong answer so it's better to use 3u methods

why do you want to find the inverse?
