Hiya! I would definitely recommend taking the time to look at YouTube videos (I found "Shemmassian"'s video particularly helpful) about the CASPer test, and brushing up on how to structure your responses in a way that's most effective. For example, (1) making sure to voice that you understand both sides to a perspective, (2) giving the main issue, (3) explaining how you would act, and (4) giving good justifications. Showing empathy in your answers is also super important.
I also would recommend anyone taking the test to really take the practice exam seriously as if you're taking the real test. That way, you have a good feel for the time constraint for each answer. They allow you to have a blank piece of paper during the test; use the paper!!! While listening to the video you can jot notes down, and also during the reflection part so you can quickly map out your answer structure.
If you have any other questions, feel free to let me know!
