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.

TIA is garbage for the ELM section. I'd put a lot of the questions at the end of each section at about a level 2 or 3 on ADAPT, and not representative of what we'll see on the exam. I had to borrow my co-worker's ASM material for the ELM section. There are more practice problems at the end of each section, and it's way more manageable than Mahler (although Mahler's practice exams are still the bomb). The regression section is about 230 pages, and I don't know how long Mahler's total regression chapter is, but his whole manual is 4000 pages.

I will say that TIA is fine for explaining stochastic processes and statistics, but now that regression is 35-50% of the material, it seems like they'd have had better practice problems for regression. I thought I knew the material way better than I did, and now I'm having to go back and re-learn everything.

Lee does a good job of explaining time series too, but the notes stink and don't contain any graphs, so I had to go back and pause all of the videos and take screen shots of a lot of the time series graphs to understand what was going on.

Have you taken the exam before, or are you just speculating on the difficulty of certain sections? I'm just wondering because I am currently using TIA.

Yes, I took the exam in October of last year. There was another person who took it at the same time who passed with a 6 on her second attempt who said the same thing. At the time, I thought she was just making excuses that TIA was not that great. I thought it was just my fault that I didnít know the material well enough, because I bombed the GLM section. While I do think thatís part of it, I also think TIA needs to work on re-vamping their question bank.
