lol Biochem is a must have,,,. at least my school required all bio & chem majors to take it.
Bio cancer & virology sound cool. Definitely take something microbio related. I took microbio and I loved it.
If your school doesn't have microbio, then deff take bio of cancer and virology. If anything it'll be interesting and inspiring.
But since you already got into medical school, why not take classes that are inspiring to you. Take some behavioral science classes to open up your perspectives and point of views? Take art history or something cultural to expand your knoweldge and to have some cultural competence. All good things for med school too.
If you like something other than medicine, take those classes now. Because when you start med school, it's all about medicine 24/7, so when will be the next time you took a course because it was "fun" or because you found it interesting?
Something to think about. 😉
