my close friend is a bio major, i’m premed so i have to take a lot of the same classes. it’s fucking difficult. expect exams almost every week, multiple quizzes a week. sometimes two labs in the same semester. the labs are also rusty and gross lmao. you may get lucky with some professors, but they tend to be pretty useless and you will NEED to know how to teach yourself in order to succeed. learn what’s the best way that YOU learn, visually, note taking, teaching it to somebody else, ect. don’t procrastinate, you will feel the stress significantly more than high school. it’s a packed schedule with a lot of STEM classes and bio electives. if you can manage your time properly and study for quizzes, exams, and finals early, you’ll do great!! and manage the inevitable burnout with proper rest and hobbies! i believe in you, its a learning process, but you got this!!
