Study.com - Optional quizzes?

[kylan11]

I just took the Business 304 exam. (1 out of 6 then I'm ready for UMPI!).
And I noticed that while going through the chapters, once I finished the first quiz of the chapter more quizzes would automatically mark as completed. So by looking at the syllabus it appears that they are optional.

However they DID appear in the chapter practice exams and also in the final exam. I saw some questions for topics I had never seen. So is it a specific bug for Business 304, or should I not trust the site when it says a section is optional?

Btw, terrible experience so far compared to what I was used to at Sophia. UI looks bad, unintuitive and belongs to 10 years ago at best, courses are more like a salad of concepts stitched together with very little direction or purpose and different narrators with varying sound quality ranging from good to terrible.

Did you complete any related courses or placement tests? I believe quizzes become optional when you've shown you know enough about a concept that you don't need to view the lesson or pass the quiz.

The sections/quizzes that are marked as complete are optional.

The rest of the quizzes count towards your grade.

And any lesson, whether its quiz was optional for you or not, could include material "testable" on the final exam.

Furthermore, your main objective is to get as high a grade possible for the quizzes, it'll leave you more wiggle room for the final exam and assignments. Depending on the classes you have, for upper level classes, quizzes are 33.3% or 100 points, exam is 33.3% or 100 points, and the assignments are 33.3% or 100 points of the total. You need a cumulative 70% or 210 points to get the ACE credit, it doesn't matter if you have 211 or 290 out of 300... a pass is a pass for most cases.
