A tutor is not able to log half a lesson, nor should a tutor conduct half a lesson.
It is not worth it for a tutor to travel to a client’s home for a 30 minute or 45 minute lesson and the tutor portal does not allow a tutor to log half a lesson.
If you did one and a half lessons, you can log the lesson as “one and a half lessons”. Make sure that your lesson length is correct based on the length of a single lesson! E.g. One and a half lessons on a one hour package will be 90 minutes, while one and a half lessons on a 1.5 hour package will be 135 minutes.
