Ahahaha same here.
Oh and i forgot about something else that happened to me. In my last week of the HSC, i had 3 exams in a row, chemistry on monday, modern on tuesday and then physics on friday. After the modern exam I was dead. Completely over trying to study/cram (keep in mind i didn't study from yr 7-11) and so slept for most of tuesday arvo, ate when i woke up and watched new NCIS + Lie to Me. By that time it was ~10.30 and i was like hmmm perhaps i should try studying a bit.
I somehow got my mojo back and crammed 1 year's worth of content in 4 hours, sleeping at ~2.30 and waking up Wednesday morning to sit the exam. I managed to get a band 6 for physics
I don't know if that's motivational though and i certainly do not recommended cramming XD
