Is 19 Units as A Sophomore Student in CC too much?

I just recently took Trig for the Summer and got an A and i think it improved my overall study habits since I was forced to study every day and go to math labs in order to obtain that A. I wasn’t that good of a student in High School but I’m doing okay with around a 3.65 GPA in college so far. What I want to know is if 19 units is too much for me? I’m forced to do this so I can transfer within 3 years instead of 4 years. And in my own personal opinion, I’d like to say that if I can’t even handle this workload then how can I handle what comes in the future (I’m a biology major)?

Calc 150 AC(4) -Calculus I- I’m average at math but I can make an A if I try super hard
Chem 111AC (5)- General Chemistry I - this has 2 labs and I’m kind of good at chemistry
Posc 101(3)–United States Government - this is online
Biol 174 (4)- Biology of Cells and Tissues- my first biology class
Danc 101(3)- Multicultural Dance in the US- also online but this should be relatively easy

It sounds a bit high but nothing too extreme.

Out of curiosity how is a Dance class an online class? Or is this some sort of history class?

yes its about the history of the mulicultural dance in the US! thanks for the feedback!!!

Is the biology course a lab course? If so, having five courses including two lab courses could be a lot of work.
