Using “Since / For” in OET

Since / For are used with has, have forms. However, they have different usage.

  • Suppose you have started doing this course an hour ago, say, 10 am.
  • It is 11 am now.

You should say:

  • I have been doing this course from 10 am.
  • I have doing this course for the last 1 hour (10 to 11).
  • I have done this course for the last 1 hour.

Study the difference:

Since For
Since + a start time For + the duration from the starting time.
She has been under my care since Monday. She has been under my care for three days.

Remember, you can use since when you know the starting time. You can use for when the duration is known.

  • Even if the action started an hour ago or a thousand years since, you can use have, have been, has, has been + since / for if the action is not interrupted
  • Can we use since in place of ‘as’?
  • Yes, but that “since” is different in usage and meaning. That’s like, “Since (as) I was too late for the session, I didn’t understand the use of since.”
