There are 2 cases where 'learning before recording' is recorded.

1) Learning before the attendance(progress check) period

It is recorded as 'learning before recording' because it was learned before the attendance(progress check) period.

The learning time is recorded as '0' because the progress is not checked in this case.

2) Learning after the attendance(progress check) period issue

EX.

• Original attendance(progress check) period: 2021-03-09 00:00 ~ 2021-03-15 23:59
• Student's learning date and time: 2021-03-10 / Present
• Changed attendance(progress check) period: 2021-03-12 00:00 ~ 2021-03-15 23:59

A student is present if he/she completes learning within the attendance(progress check) period.

In this case, if you change the start date and time later than the learning date and time,

the student's original learning record will be changed to 'learning before recording' and 'Present → Absent'.

In this case, please check the attendance manually, or change the start date and time of attendance(progress check) period to the original ones.

(Caution)

• If a learning record exists, please do not change the attendance(progress check) period.
• If the start date or time has already passed, please do not change it.

+ If a student has completed VOD learning before the period change

Since the learning has been already completed and the VOD play bar has moved to the end,

when learning again within the changed period, the play bar does not move any more, so the learning time is 0 and it is recorded as 'learning complete'.
