Study.com Placement exam

[gremlinbrawler]

Study, what is the maximum percentage that one could place out of a course? Could someone who really knows a topic well be able to test all of the way out of a course?

The study.com placement test page that Btaylor89 just posted a link to says that you can earn up to 100% course progress through it. So supposedly all of it except the final.
But it also says at the bottom that you have to take multiple placement tests to do that because each one only covers a portion of the whole course.
