Should I take less units for my first semester in College? (18 units)?

[Cassie]

As of right now, I am enrolled in 18 units as a first time freshman, and I am majoring in Exercise Physiology. My goal is to graduate in 4 years and go on to grad school to become a Physical Therapist. I am considering taking 18 units but I'm not quite sure if this schedule will be too difficult and overwhelming? Please answer if you were/ are a college student and have experience in this area. Note: I was an average hs student. Maintained around a 3.5 Here is the schedule we're looking at:

-Intro to Dance: Survey course that reviews dance as an art form in both Western and Eastern cultures, to include ballet, modern, ethnic, social dance, jazz and musical theatre. (no dancing, just lecture)
-History (reading intensive)
-Journalism (writing intensive)
-Religious Studies
-African American Culture
-Disability and physical activity in the media

....if you don't think I should be taking so many units, which one do you suggest I drop?
