I had a class and the student entered the classroom at 16th minute when I was about to tag him absent. I asked him if he wants to continue the class he said yes. We conducted until passed 25th minute. Can I post a lesson memo? 

Lesson memo can be posted if there was at least 10 minutes uninterrupted lesson, after the student have entered in AC until the end of lesson time.

If the total number of minutes is not 10 or above, lesson shall be tagged Student Absent.
