Study.Com Pretests

I always wondered this, and maybe someone knows the definitive answer.

I remember completing 100% of the chapter quizzes and scoring 100% on all of them. Yet in the score box is said you scored 92/100 and because of this need 59% to pass the final.

If I scored 100% on all of the chapter quizzes, then how did I get a 92/100?

Only thing I can think of is I did a few pre-tests and did not score 100%, was I graded down for not bringing those up to 100%?

I'm done with study.com, but it is something I was curious about.

If you took more than three attempts to get to 100%, only your first three attempts can be considered in calculating your quiz grade. That could be why.
