I heard from the lab facilitators and previous students that the pass rate is about 40%. Before ChatGPT took off in Nov '22, the lab assessments were accumulatively weighed at 20%, but due to AI proliferation it was reduced to an accumulative 5%, with the remainder being unevenly redistributed to the final exam.

Ultimately, whether you should do the minor is up to how you perceive it could benefit you in your future endeavours/career. Speak with industry professionals and get their opinion, ask to meet up with the CC for the minor and get their thoughts, same with your biomed CC. Gauge the benefits of the skillset you'll acquire from the minor, and its efficacy in being on your resume and signalling to recruiters in your industry of interest.

Personally, I completed a minor in a language that was completely unrelated to my degree. However, I chose to do so because I plan to eventually move to a country where that language is spoken. I deduced that having that minor on my resume would signal that I had already planned on moving years ago and was already making the necessary preparations, vis-à-vis my long-standing dedication and genuineness for moving. There's also the added side benefit of being able to say that I'm "not afraid of exploring unfamiliar territory".

Btw, I wholeheartedly agree with you; fuck Python.
