I set an exam for I compiled an exam for I drew up some questions for I put some questions together for ...used by native speakers. Well ok, some of them perhaps. But....do you mean you invigilate? = supervise students sitting an exam to ensure they start and finish on time, do not cheat, etc.?

Hey Muhammed Qasim, Your sentennce uses the verb conducted in a way that is not very common. Formally, I might say that "I administered a math exam for my students." If you also created the exam, you might say, "I designed and administered a math exam for my students." Does that help?
