For 2021-2022, The UBC academic calendar added course requirements of DSCI 100, STAT 201 and Stat 301 for Major in Statistics. If I joined UBC in the academic year 2020-2021 of earlier, do I have to take these course to complete the STAT major spec?

If you started in the Stat major program in the 2020-2021 academic year or earlier, you can choose to satisfy the academic calendar requirements for either the 2020-2021 academic calendar or the 2021-2022 academic calendar.Anyone admitted to STAT major in May 2021 or later is required to take DSCI 100, STAT 201 and Stat 301.
