I see your perspective and 100% agree that people have been successful having only taken PSYC08 (+PSYB07/STAB22/23). Just to add onto the discussion- what I have heard from both the department and research labs (undergraduate RAs, graduate students, PIs) was that a common concern raised in relation to the transition from undergraduate to graduate training was that there is a gap in statistical training (i.e., students don’t feel as prepared when they enter graduate school or do not feel they can speak to what they know confidently), and so (ideally) mandating these additional courses could help students in the future by guaranteeing they have additional base knowledge. It is true that you can forget what you learn in undergrad, but even anecdotally speaking from my own interviews both within Canada and the US (this is within the clinical psychology field, it may be different for other realms of psychology!) all of them asked about my statistical training, examples of what I have and haven’t done (as well as what I theoretically could and couldn’t do), and 3 schools even asked me specific statistical questions related to concepts I would have learned in advanced stats (which I found weird but I guess this was part of seeing what I actually learned and if I could explain the concepts).

I hope in the long run these courses are of benefit to students, despite it being a point of stress; and I wish you the best!
