Touch wood, but I’d be amazed!
The general ability one was 8 mins I think. It’s not too bad, make sure you are happy with working out percentages and how to do those picture sequence questions and you’ll be fine. There are some verbal ones in there that involve reading a passage of text and giving the appropriate answer. Again, pretty straightforward and the practices you get to do are a good indicator of what is expected.
The Mini SCAAT is fine, it’s letters not symbols. There are 3 parts to the test and the practices you get to do give you a really good idea of what you’re dealing with. Don’t worry about it all too much, I’m sure you’ll be fine. Just make sure you’ve got peace and quiet, no distractions and that you’re happy with all the practices. From memory you can still exit after doing the practice, so if you think you need to brush up on anything after that you still can.
Good luck with everything!
