PDI offers two course format options: flex-time courses and semester courses. Course content is identical between flex courses and semester courses. The main difference between the two options is that you can take up to one year to complete a flex course, whereas you must be finished by the end of the semester for a semester course. A flex course is only $112 with the discount (regularly $149). A flex course with graduate-level credit from UCSD is only $285 with the discount (regularly $379). A semester course is only $150 with the discount (regularly $199). A semester course with graduate-level credit from UCSD is only $322 with the discount (regularly $429). Both flex and semester courses are approved for graduate-level credit through UCSD Extension and are often used to satisfy salary advancement or credential renewal requirements.
