The majority of the CREA courses run in blocks of 10 weeks. You can start a CREA course at 3 different points: end of September 2022 (block 1/autumn), mid January 2023 (block 2/winter) and end of April 2023 (block 3/spring). There are exceptions like the week courses in July and August (block 4/summer) and Crash Courses (1 day). Check the course for more info.
