Ib results

I've been putting soooo much effort into my IB art score, and I genuinely thought I would get at least a 5. But no, because of my shitty exhibition, I got a 4. I'm so annoyed my teacher graded my Process Portfolio and my Comparative Study as 7 and 6 worthy to my face and then turned around and gave them 5s. Why didn't she give me a chance to fix it what the fuuuuuck. It's actually driving me mad I hate IB. Luckily, I got a 7 in English and a 6 in History, the only subjects I actually cared about, but still... it's the principal of it...
