Please correct me if it is wrong...,

"Do you know when our next class is starting ?"


"Do you know when our next class starts?"

Thanks in Advance.


Being very careful, I'd recommend

Do you know when our next class starts

because starting is not a process that takes place throughout an interval and so will seldom if ever strictly warrant a progressive tense.

In actual practice, however, very few people are that exact in their language, and you will hear both forms used by well educated native speakers interchangeably.
