· Regular Class(Trial Service)

Learners who have signed up for Maalsam could receive a trial class service for one month (4 weeks), after the start of the regular class.
During this period, learners can receive regular classes through accurate measurement for Korean proficiency by Korean tutors.
The learner would be converted to a paid service, otherwise it should be classified as a member of free class, when the four-week trial class service ends.

· Regular Class(Paid service)

Regular class service that learners receive by converting to paid service after end of trial class service

· Free Class Service

If a learner who has passed the trial class service period (4 weeks) does not switch to a paid service, the learner could apply for a free class service.
The free class service is a special class, not Maalsam's regular class, and the classes are taught by volunteer tutors.
If the application is approved, the learner can receive free classes for one month (4 weeks), and when that free class ends, they must apply again.
However, the free class service might have a longer waiting time or end early depending on the circumstances of the volunteer tutors.
