Guys I've got a secret straight from the exam paper itself. There will be an 8 mark question asking you to write a belonging creative.

The stimulus is something like :
"My name is hydrogen. I live on the planet haber. All my life I've been searching for my soul mate, the perfect nitrogen but I can't find her. I'm so lonely...."


Yeh it's weird right? Apparently english exam writers were annoyed at the AOS changing so stole the chemistry exam and changed it... good luck
