I you look at the first list ( http://logicmastersindia.com/forum/forums/thread-view.asp?tid=60&st... ), A/B/C in "#Of Players" column means "#of players with Bonus Points / #of players with Non-Zero Scores / #of players who started the Test". So just watch out for higher values of A there
But higher values of "#of players with Bonus Points" just means the overall set was easy (or very few difficult puzzles). All the puzzle tests have some amount of easy puzzles.
