You'd minimize information loss by giving the actual scores.
The argument is 'grading on the curve' vs 'ABCDEF'. The first way is fair, but it promotes extreme competition to be in the top 1% (or 'The Senior Wrangler', as we used to call it), which may not be desirable. The second way hands out random bonuses and penalties to individuals near the arbitrary boundaries.
I was in the top 25% of my year in terms of marks, I believe. I was a 'Senior Optime', or 'got a second'. A class that stretched from around 25%-75%.
Not bitter, or anything.
