Student or Learner
I don't know which one I can use in the following contexts:
a. The class/classes begin(s) too early. (meaning: I'm attending an English course that is held on Thursdays and one lesson lasts two hours. Should it be singular or plural, or both are acceptable?)
b. The teacher often comes late to the class/classes. (meaning: I'm attending an English course and the teacher is often late for work.)
Thanks for your replies.
