what does it mean exactly where it says:
- Repetition of any preparation course more than once results in automatic denial of admission to the major.
and
- Repetition of more than any two preparation courses results in automatic denial of admission to the major.

If you get a D/F UC doesn’t give you credit for the class so in order to satisfy the prereq you need to take it again. So get a D/F in the same prep class twice, or in more than two different prep classes, and you won’t be admitted to the major.
You can’t repeat classes in which you get a C or better (well you could, but UC ignores the repeat grade)
