Hey I'm down at the Gong during weekdays for uni, I live at International House (near north gong station) during the week and head home on the weekends and holidays, so if you want tutoring during the holidays it will be tough cos I'll be down in Sydney during that time.
But if you're
really desperate I'd be happy to help you during Uni session. I haven't tutored for any of those subjects but got Band 6 for Bio and Chem.
In regards to "deer"'s request, I did 3u and 4u Maths so I might be able to help with 2u.
I tutor for Physics currently, (which was my best subject in HSC) if anyone from the Gong needs help with that, but again I'll only be available weekdays during Uni session. Since I'm not experienced at teaching Chem, Bio and Maths, I'll charge $12 an hour.
If you're interested you can contact me via email:
