There's no right or wrong answer here.


But when you ask the question, then it's obvious you need to attend lessons like the rest of the population in Malaysia who can't be arsed to self-study, only wait to be spoon fed by teachers.

Those who have the true drive/enthusiasm would've already started learning by themselves without ever asking this question.

If you have to ask this question, then you have to take classes, period.

For the rest of us who're able to learn without teacher/classes and just rely on youtube and the internet, it's not wrong either. There're enough of video examples showing the proper way.
