Definitely agree with this. At least for me when taking undergraduate math, once you get to the proof based stuff, often times seeing the answer was in no way helpful. You either knew you proved it correctly or you weren't able to do the mental gymnastic it required to get there and seeing an answer was likely not going to help. I usually just had to re-read the book and try different things, take a break maybe, or something before I would finally get the intuition or whatever to really grasp it. For calculation based math, which this course sounds like and based on a sample test I looked at, more or less is, having some subset of answers would definitely be helpful. I am not sure why they would make it more obtuse than it needs to be. I thought the course I took on multivariable calculus and linear algebra were quite easy but the number of people who dropped math entirely after those was pretty drastic. I don't think you really need to make these classes unnecessarily hard to weed people out. They'll do it themselves anyway.
