In person classes are the way to go!! Especially those with labs. I know it’s hard when working full time but if you truly want to do the best I think In person classes is the way to go. I also took BIO 156 at Rio and it was really hard. I passed with a B. I , too felt like it was disorganized and it was hard to know exactly what to study for tests! I’m taking BIO 201 at MCC in person now ? Online classes with labs do not work out for me lol
