It's the guessing adjustment used by the CAS. For an incorrect answer, they subtract one quarter of the point value.

It could change ofc. I recommended people this in the past and I still stand with it: Focus a lot on GLM. Know it well inside out.
I did a run through of the Spring MAS-I exam this weekend, I did notice that the time series questions were very simple as you said. I thought the new statistical methods on MAS-I was a little rough, there weren't a lot of practice problems on the new material.

I missed 2 on GLMs and one was because I forgot to square the answer since it used the square root link function, I did generally hear the GLMs section was rough from other students.

I took some advice from the forums and focused on it while learning material and periodically reviewed GLMs, I also feel like Mahler does a great job at explaining GLMs in general. If you're struggling with GLMs I highly recommend his manual.

So, I'm new to CAS exams.

Is it better to guess or just leave a question blank, like if you have 100% no idea what to do, hypothetically.

That seems like a pretty easy exam P exercise in expected value.

This is my first CAS exam as well. If you have no idea, and feel like you're doing well on the rest of the test, leaving it blank seems like a good idea.

I'd probably guess if I can eliminate 2-3 answer choices as incorrect, or if I felt the test was altogether not going well. The point of the adjustment is to eliminate the advantage of blindly guessing, so in theory you have a 20% chance of getting it right if you guess; if you guess on 5 and get 1 right and 4 wrong your net points are zero with the deduction for incorrect answer.
