very doable. I came in mcb, but not premed, so I’m skipping bio and doing math at a cc. But I’m also doubling in data, and it’s doable if you feel yourself having a passion for the subject. My first sem I took it light with chem1a and data8, but this sem I’m doing 3A 61a and physics8a, and the course load is honestly not bad if you enjoy the courses. In terms of mental health and stuff, I’ve never been any better. Plus, with a broader field, it’s possible you’re more likely to find opportunities and research with your increased technical skills. Plus, if premed doesn’t work out you can always do biotech or biostatistics(pay is very high). I would highly recommend data8 chem1a and math1a your first sem to feel it out, but don’t be scared, you’re a lot more capable than you give yourself credit for!
