Must've been serious. Is it going to affect you in the future? D:Minimise the damage. What would you fall back on if you had 10 units? Nothing. You'd have to work super hard to get back to where you would've been without the tragedy.
With more than 10 units, let's say a tragedy happens. Your marks take a hit. But because you have more than 10 units, you know that one subject isn't going to count - and you go forward with a mental note that you haven't completely stuffed up. For me, my maths marks suffered because in maths you need constant revision. But because I had Physics and Legal Studies (what I deemed my 'extra units') - I was able to not worry about the maths units because I had these 'extra units' to lift me back up to a respectable ATAR.
Funnily enough, my 'extra units' didn't end up counting!
Eddy, one of my valves was making blood go the wrong way. 'Leaking' I believe is the term?
