It’s been almost 4 years since I started orthodontic treatment with the teacher. It was supposed to be finished in 2 years, but the teacher is extremely meticulous, so we did this and that and it kept not ending. Highly recommend for exam-takers or people who pursue perfection. Of course, you can also choose personally to stop at around a 90-point level midway. But they really are meticulous.
