I hate you ALEKS!!!

ACE credit comes from the assessment. If you have 70% of the pie completed and get a 65% on the assessment, you aren't finished. If you have 37% or 51% or 64% or any number under 70% of the pie finished and get 70% on the assessment, you are finished.

Also, I don't think anyone has mentioned it but there are only small sections of the pie open in the beginning. This helps build a foundation for the more difficult problems. As you master the available problems, more and more of the pie will open.
