UCSB - Course Waitlist

Hi

For those who experienced waitlisting for courses, how likely would I successfully add a class (MATH 8) if I’m at 20th position on waitlist? Should I drop and take another course?

What is your major?

My major is physics… that’s why I’m not prioritized and had to wait until pass time 3.
