I feel your pain
I did
-Visual Arts
-English Ext 2
-Music 2 (Composition Elective, so two compositions & two journals)
-Music Extension (Composition Elective, again, two compositions & two journals)
So I did 6 all up.
What advice I'd give you is to start
NOW. FUCK! START NOW!!! NNNNOOOWWWW!!!
or at least, realise that they're pretty much due all at the same time. Drill that in your head. Make yourself finish quite a bit early so you can actually sit down and proof-read ext 2 english one more time, polish your art majorwork etc. Which often takes more time than you think it does.
As for being someone who I could relate to, I bid you good luck! I actually did incredibly well in my majorworks last year, I got an E4 somewhere, E3's and a band 6, (which was unfortunatley dragged down to a band 5 cuz of school assessments but don't you ask me about that. I blame my teacher damnit).
What I'm saying is, it's also very possible to get the highest band for many of your majorworks.
So don't think your amount of majorworks = doom.
If you haven't got ideas by now, I've been advised that you should intergrate them, like I had a postmodern thing (for a while anyway) going on in all my majorworks, which just made it a whole lot easier, cuz I could write the same smart crap in my majorwork (or in other words, gather a complete understanding of certain concepts).
If you don't that's okay. My art majorwork was based on my experience of the John Mayer Concert in April, my english was postmodern poetry on God and Adam while Adam was a pile of dirt, intergrated with other religions & languages, as well as my music, which is a lil hard to explain here cuz there is a WHOPPING FOUR OF THEM.
Anywho, best of luck. You creative genius you! Just be so organised, but give yourself creative freedom
All the best!
