Is College Biology, Chemistry, and Algebra too much for one quarter?

I was wondering if College Algebra, College Chemistry, and College Biology is too much for one quarter? Each class counts as 5 credit hours, plus, the bio and chem class have 2 hour labs. I had to take the remedial math classes, and passed with A’s, so I am not too worried about the math. I have to meet a “New” deadline made by my school in order to get into my program of study before next year, or else I would have scheduled different.

I would appreciate any feedback, or advice…Thank you
