How hard are Study.com Finals?

[mysonx3]

I'm a little concerned that skipping over the quizzes I don't take will hurt me on the final, so I'm wondering how hard the finals are and how well they usually match the content of the previous quiz questions?

I see from your signature that you took Discrete Math. How was the final exam?

I was a little worried about it because it was the only Study.com class I've taken where I had some difficulty with the content, but the final wasn't a problem. There were very few questions from the more dense sections of the material (aka the ones without videos), and when there were I pretty much just went with random guesses. Still got 87 out of 100 if I'm not mistaken.
