Non-standard and Intensive Courses
Courses can be offered at a shortened, accelerated pace, in which the credit hours assigned are the same as standard semester courses. These courses require the same total amount of instructional and student work time as full semester courses, even if delivered within an accelerated time frame. Drop deadlines are unique to each course and can be viewed in UCDAccess in "My Class Schedule" under "Deadlines."
