I believe that deserving or not doesn't really express your thought exactly.
Let's look at this from the other point of view.
You have spend hard time preparing for your exam.
- You were looking forward to a thorough exam, a difficult adventure, each step of which would remind you of how good you're prepared.
- You were looking for something that made an objective assessment of your knowledge.
- You were going for a "checkpoint" in your education which would be a proof to yourself that the time you've spent on learning is justified and you have indeed make a good progress in maths.
What did you get instead? An easy test, which doesn't require detailed answers and doesn't really say anything about your knowledge that you could be proud of. It's as learning how to drive a race car in tough conditions on a twisted road, and once it's time for an exam, be presented with just a straight to "check" your knowledge. Needless to say, that wouldn't check anything and wouldn't prove you're a good racer.
What conclusions can be drawn?
The fact that your college didn't bother with making a more objective test may say a lot: they probably don't care about students as much as you expected them to do, or this college is not a such a high-tier educational institution as you would thought it is and graduating high-quality masters is not something they are fighting for. This may sound too harsh, but be ready to get an unconcerned response once you ask your teacher for a more representative exam.
You should have a better understanding of why you're actually studying any particular field. A good mark is not a good goal; if everything you did want was a good mark, you should also ask yourself a question: is it worth it? A rating-based system (gamification) is a nice thing in education and it often works really well, stimulating students to "beat" each other in this game, but you should also look outside this game, you should have an expressible goal of your studying and realize why exactly you're spending time in this topic.
You've passed an exam, and did it with a good score. However, you're not really happy about it. You just suddenly realized that a good score is not a solid goal: you're not the only one who should be willing to get knowledge, but the teachers should also be concerned about teaching you. There's different ways of judging your knowledge in educational institutions. Ones just check that you know at least something and you're good to go, other do really care of the quality of educations. And both of them have their verdict expressed via a mark from 0 to 10, but only one of these marks is actually valuable - the one that was hard-earned in the college that actually wanted you to become great at this topic.
That said, I would suggest you to try working on any project that will utilize "the mighty powers" you've acquired while studying, it should greatly improve your overall satisfaction, reduce stress and the number of times you ask yourself "why am I even studying it at all"
