I'm currently doing the mind and morality course and it is a worthwhile experience and you should just try! They don't focus on one subject but you as a student as a whole. So go for it!
Good luck =]
English tutoring at tipps is alright.
I heard Matrix is really good. But a bit pricey.
However my friend who did the HSC last year said that a private tutor for English is really good. You can give that a try.
Nahh pre-uni is only good in primary years, like for kids getting ready for OC or Selective. James An too. Yeah their results for selective school are freakyy! Everyone in my school went pre-uni for primary.
heyy yehh I go there now and yeh it's a waste of time. Believe me I want to quit. Get a private tutor for english. That's the best option i think.
But go there for maths. =]
