No comments on the Oxford comma plz

Is that phrasing a genuine way to explain the following facts?
-In the first semester of Legal Writing, we were handed a list of ranges for the different grades. A's went from 60 points to 65 points. My memo was graded a 65 and was included first in a packet of exemplar exams. I never received a number score for my grade the second semester, which was an A; there were no A+s given.
-In Property, my professor did not tell us the range for raw numbers and did not assign a "best exam," or put up the best exams for viewing. Instead, he wrote a feedback memo that quoted from a number of exams. My exam was quoted from most frequently and half of the answers were quoted in their entirety; this was done for no other exam. I got an A and no A+s were given.
-In Civil Procedure, which, like Legal Writing, was a year long, my exam was one of two to be released in the first semester as exemplary of a well-written exam. In the second semester, the professor did not release exemplary exams. I received an A, but an A+ was given to someone else.
I want to mention this information on my resume but it's a little tricky to figure out and to do genuinely. When people say, "wow, you had the best exam in all of these classes?" I feel a little uncomfortable. My school doesnt' give out "CALI" or "Book Awards" or whatever, so this is all I have to work with. Ideas?
edit: ideally, I'd like a scenario when asked about these exams that I don't have to look like I'm backing away from the statement and saying I was puffing on the resume. I'm proud of the achievements but not sure how to frame them.
