The wording which indicated the number of attempts made throws new users all the time. I think this can be improved by making a small alteration, see the suggested revision below:
4 Students have made 4 attempts
(In this example the actual position is 4 students have made 1 attempt each, most people read this as 4 students have made 4 attempts each).
4 Students have made a total 4 attempts
4 Students have made 4 attempts in total
