Hi, I can't grasp the meaning on whether I should use a comma before which in the sentence below:
I studied maths in university, which is when I also taught mechanical engineering.
If the above is a whole sentence, do I need a comma before which?
The clause looks essential but its at the end so it looks non-essential at the same time to me
