i like the design of 8200au
imo just use 8200au for everything except for combinatorics/anything related to combinatorics (including 4u for certain proofs with binomial/complex)
oh if I have to go to sydney unfortunately you'll have to pay double
so $4320 ($540/hr for 8 hours) + flight costs
genuinely tho, stop wasting your time on bos
if you're so sure you can get thru the content in 8 hours, just try doing it yourself and asking for guidance on conquerhsc, nswmaths...
I got a 98 in Math advanced, haven't graduated tho
I'll tutor for around $300/hr for 8 hours but I'm willing to cut it down to $270/hr just for you my friend.
