Humanities is very simple, probably the easiest class you are going to take. So I would pair that with a psych and English class or psych and sociology. I don't know what pre requisites you have to take, but I had to take 2 psych, 2 English, 1 humanities, 1 sociology, A & P 1 and 2, and Intro to Microbiology. You I would take A&P either by itself or pair with humanities. micro take by itself or with psych. You really can pair any classes together as long as you pair your easiest classes with all of your bio classes OR take your bio classes one at a time.
