Are these courses graduate level?

What about this. It says 1-99 is Freshman Sophomore and 100-199 is Junior Senior.

Special enrollment requirements for courses numbered 1 to 99, 100-199, and 900-999:

In lower division instruction (1-99), students must be high school graduates with a "B" average or one year of college, or consent of instructor based on special attainments (i.e., a superior high school record, special competence in a particular subject matter area, or other recognized criteria). In the upper division (100-199), two years of college or consent of instructor based on special attainments is required. There are no age limitations or restrictions in preparatory and high school level instruction (900-999).
