There are two midterms and two final exams. The first semester midterm covers Units 1-3, the first final exam covers Units 1-6; then, in second semester, the midterm covers Units 7-9, and the final exam covers Units 7-12. The second semester final builds builds on knowledge from units 1-12.
We recommend the exams be taken after completion of each set of corresponding units. If the exams appear out of order in your LMS, you are welcome to adjust them to the correct chronological position.
