I wrote the Canadian dat on Saturday too.
I found the sciences were extremely fair and didn’t have any issues, just got stuck on one of the Mendelian cross questions. Chem was super easy.
PAT I thought was really tough on keyholes, really hard to find 1 specific answer and those rock keyholes are insane imo. Rest wasn’t too bad.
RC was definitely my worst section. I found it really hard like you said, spent a ton of time on the first passage and second and was really short on time for the last one. Really strange questions and I couldn’t see a clock and before I knew it she screamed 5 minutes left. I’m praying for a miracle on that section lol.
