Should I take 16 credits next semester?

I am debating whether I should take 16 credit hours my next semester and need help deciding!

My schedule would be:
Bio 2
Chem 1
Trig/Precalculus (combined into one class)
Stats 1

Would this be doable? Please help me out!

What is normal for your major? 16 credits would be okay as that is normal, but would two maths and two lab sciences be a good idea? Given that you are taking Pre-calc as a college students tells me that math is not your strong point so I am not sure if two would be good. Could you take a humanity instead? or are these classes pre-reqs for others? I would talk to my college adviser about this.
