ur not alone. I did much worser than in my prac exams ππ, and quite honestly I don't like the way vcaa structures spesh exam 1 since students are awarded more for their algebra skills than their understanding of the content. The downfall of making a relatively 'easy' (I'm hearing mixed responses from my friends about this) exam like this year's is that now those who may not know understand the content could also get higher marks than someone who frequently makes silly errors but are very knowledgable.
Regardless, there's not much we can do now, and just hope we do better for exam 2. Best of luck!
