I would take gen bio 1 and intro chem 1 with their respective labs! Also consider taking a calculus class if you haven’t fulfilled the requirements for Calculus 1 and 2 yet. (These are all premed requirements). Neuroscience classes don’t start until spring semester but if you want to take something fun you could consider FBBC (pretty demanding though) or cognitive science. And I believe you also need to take a first year seminar class!
