So, how does grading work?

I'll be starting a BS in Computer Science this January, and I was wondering how the grading system worked and if it was similar to Straighterline.

For example, a number of quizzes/exams and a final proctored exam (Like the Intro to IT course through Straighterline)

Or is it just one big final exam that determines if you pass/fail.

Thanks for your help!
