Crippling self doubt! (aka starting college at 40!)

[Merlin]

I thought with Aleks, you take a course and then once you're at 70%+, you take a test and if you score above 70%, you're done. Is that how it works or no?

It used to be that when you hit 70% on an assessment or knowledge check you were done and you could just request credit. Now, when you complete an assessment (either the initial assessment or a knowledge check while you're learning) you will be prompted to take a second assessment known as an "ACE Knowledge Check." This additional assessment requires the use of a custom "lockdown" browser, which is intended to ensure academic integrity by locking down your system while taking the assessment (making it effectively semi-proctored). In any case, if you can complete the ACE knowledge check within the given time limit and achieve at least a 70% overall score, you pass the course and can submit the request for credit through ACE.
