Hey for music, how did you study and do so well at it?
Ummm... tbh I didn't study for music :s
I analysed 3 core piece and 3 additional topic pieces and went into the exam knowing that :s
however, I don't really know if you would call this studying but i did:
1 sight singing everyday (just so I got good at it, find random things on the internet and stuff that you can do) - if you absolutely can't sight read then you should learn to identify intervals first, i used to use songs and sometimes still do (m2 - chromatic scale, M2 - diatonic scale, m3 - axel F/crazy frog song, M3 - Oh when the saints, P4 - national anthem, tritone - the simpsons. P5 twinkle twinkle little star, m6 - (no song i just learnt it eventually), M6 - my bonny lies over the ocean, m7 - no song, M7 - always sounded incomplete as it's a leading note (like a perfect cadence), P8 - some where over the rainbow) ---- this also works for melodic dictation when you're first starting out
1 melodic dictation regularly
What I already had done was 1st-5th grade music craft which was really all I needed
What you should learn to identify would be things such as
Keys (learn how to draw a circle of 5ths (it really helps a lot), key changes/modulations, terms (In class I built a dictionary of terms that I hadn't seen before), names of instruments (this should help
http://www.library.yale.edu/cataloging/music/instname.htm), know a bit of background about a few composers, know a bit of backgroud about the main eras (baroque, classical, romantic, modern and obviously australian), how to transpose between clefs and instruments, what key + register each instrument of the orchestra is in (+ things like the saxophone, tuned percussion, etc)
I recently explained a bit here (not in too much detail though)

and also here, you should know a bit of this as well

I'm sorry that I couldn't really be of much help but don't hesitate to pm me if you have any specific questions or need help in anyway
(or alternatively post your question on the music forum, i check there regularly)
