"Class" and "classes" are both used in some contexts.
e.g.:
He had math and science class today.
He had math and science classes today.
She has class all day on Friday.
She has classes all day on Friday.
I found enough usage of each to assume they are are all viable. But, grammatically it doesn't make sense to me. Can anyone provide a rule or reason as to why "class" can be used in these examples?
Thanks!

He had math and science class today. To me this says he had (at least) one class today. The name of that one class is "Math and Science".
