- "When will your studying end/finish/over?"
•replace studying with "studies"
•You can keep "end" and "finish" as they are and the sentence is correct
•If you use "over," you must put "be" before that word.
• Same for the sentences below! Except in the US, "lessons"/"university" are less common than using the general "college."
- When will your lessons end/finish/over?
- When will your university end/finish/over?
