Study.com Math 108: Discrete Mathematics - Optional Quiz and final exam

[spohara]

I am learning Math 108 Discrete Mathematics on Study.com, and I found some quizzes are marked as optional. like in Chapter 6 there 3 quizzes that jumped to statistics 101 Principles of Statistics. May I know if those parts will appear in the final exam?

And will the final exam come with all new quizzes instead of repeated in Chapter Quiz? Because I see Chapter Quiz is repeating with each lesson's quiz.

Thanks in advance!

I'm working on the same course.  Generally what I've found on SDC is that there are a solid chunk of questions on the final that are exact copies of quiz questions, another bit that are the same question asked a different way and maybe less than 10% completely different questions (or maybe just ones I forgot about I dunno).  As far as optional, I do the lesson, I don't do the quiz.  Not sure if they'll show up on the test, but the understanding can't hurt.
