Students often don't notice when a teacher corrects their mistakes.
Look at this example of a conversation between a student and a teacher:
Student: I gave the IELTS exam last week.
Teacher: Oh, you mean you took the exam last week?
Student: Yes, I have given the exam twice. (should be 'taken')
The student doesn't notice that the teacher is correcting a mistake. Your teacher can 'give' you a test or an exam, but you 'take' or 'do' the exam.
When a teacher repeats something that you said in a different way, you probably made a mistake. Listen carefully, and try to correct yourself.
