Hello!
Most students choose to take Bio 171 and 172 in sequence, so one is usually taken before the other (in no specific order). However, it’s totally okay to take both at the same time if you feel comfortable, since each class focuses on different aspects of biology. As for the rest of your schedule, it definitely looks manageable!  If you’d like more information on how each of these classes are run online, you can check out our new blog post: https://premedhubumich.com/blog/
Best of luck in the new semester!
