Therefore.. taking a master's might not be the best way.. I don't understand the inflation.
Well, I think it depends. For instance, in CSU's 1 year plan B (non-thesis) MS, the set of courses you would be taking include some upper division ones and graduate ones that may or may not have the same inflation as typical graduate courses.
I think the thing is, many graduate level courses are more based on subjective things like contributions to class discussions and such, rather than objective ones like exams. Not to mention that most graduate programs require students to maintain above a 3.0 to stay in good standing, and most graduate students are pretty bright anyway*.
The exams we do tend to have are more gauging our abilities related to being able to solve research problems. For example, in my population and quantitative genetics course, grades were determined by 2 exams. The exams were take-home exams, with some questions being of the "Here's some data, compute the following values for it and then discuss the implications of your analysis" type, and others being of the more theoretical type, like "What is the heritability of sex?" or "Design a study to find loci for leash-pulling in dogs." So it's less about your ability to retain and recall than it is about your ability to reason through a problem logically, which in a typical lecture based vet curriculum is not how most classes tend to be run. So they might be thought of as poor predictors of
success in veterinary school** based on that. I only wish that the schools could see that comparatively to others I got a higher grade, even if 30% of the class got A's.
*in many graduate courses, the scale usually ends up ending at a B- or so, so an A- is basically like getting a B, and B+ and B are basically like getting a C, and B- is basically failing since we have to maintain above a 3.0
**though IMO it would be a good predictor of success in actually being a veterinarian
