Bro, you got this! Half yearlies is just a great way to practice and prepare for the HSC. So do your best, then once you receive your results, you'll know where you need more work in. Good luck in em'!
Ahhh man, that sucks! Hope you get better soon, so you can get back to study.
I basically go to uni and work on me assignments, hang out, sleep in the library, or just study. Right now uni > home
