If you enrolled to BOSH SO1, BOSH SO2 and COSH, you can take the course at your own pace as long as it will be finished within the given time frame.
Once you have the access to the module, the course will be made available for 30 days except for SO1 which is available only for 5 days. It is the directive of the DOLE-OSH Center to conduct surveillance to the students during the whole duration of taking the course. Thus every time you will access the course, you are required to join the J3 virtual zoom training room (12 pm -10 pm, Monday to Sunday) provided by the team.
