Hi,
3 months = 12 lessons (2 hours each). You can shorten the course by attending few sessions a week. For example, twice a week = finish the course in 6 weeks or 3 times a week = finish in 4 weeks.
The session is all 1 to 1 private lesson. Unless u have your own group of friends else it’s not that convenient to mix with other working adults as they have different schedule weekly.
BTW, certificate will be provided upon the completion of the course. Our learning centre is registered with the education department since year 2004. Cheers!
