Thinking of taking 19 units in spring. Any advice?

Hey guys,
so I’m a community college freshman and in spring I’m thinking of taking 19 units. Now the problem is that my classes are split between 3 different colleges and I’m going to be working too. The classes I’m definitely going to take:
-C programming (3)
-English 102 (3)
-Physics: mechanics (calc based) (4)
-Multivariable Calculus (5)

The class I’m thinking of adding on:
-Molecular and Cellular Biology (4)

Now I was thinking of taking bio instead of calc, but I thought I shouldn’t skip a semester between math classes. The matter at hand is whether I take Bio now or wait and take it in summer with General Chemistry I (6).

Thanks guys!

Take it now versus over summer. Taking a 6 unit class over summer will be a ton of work as it is. I’ve taken 19 units in a semester before while playing college sports. It’s do able, just be prepared for the work load.
