There are IELTS schools everywhere in Guangzhou, which are distributed in various administrative districts. I know 44 schools, and there are many schools in Tianhe Yuexiu. But do you want to tutor IELTS in general or specialize in single subjects? Many IELTS schools offer different courses, some with 6.5 points, some with 6 points, some with one-on-one and some with small classes, depending on the demand.
