Student or Learner
I was given an answer that goes:
I left school 2 years ago, when I finished my IB Exam. (since)
And I am asked to create what the question might have been in the form of present perfect using since.
Is the following a correct one? Please advise, thx soo much!
Question: Since when have you left school?
If you try to start with the word 'since', you end up either with a mistake (like yours) or a ridiculous periphrasis (which I'm not sure would be acceptable; it certainly wouldn't be used, even in it is ): 'Since when have you been in the state of having left school?)
