A teacher who codes.
A school that measures.
GrammarMetric is one teacher, a small classroom in Bangkapi, and a stack of software built for the students in it. You will always know who is teaching you.
Hi, I'm Charlie.
I teach English, IELTS, and TOEIC at Santisuk English School in Bangkapi, Bangkok, and I build the learning games my students train with. GrammarMetric is the whole system: honest placement, small live classes, and practice tools that students actually open at home.
Everyone is welcome here, whatever your first language. Students come from across Bangkok: Thai and Chinese speakers, expats, working professionals, university students and school pupils. Classes are taught in English from the first lesson, at the level you actually are.
- Every class is mine. You are not handed to a rotating pool of teachers between terms.
- Placement is honest. I will tell you if you are not ready for the class you asked for.
- The tools are built here. When a student needs something that does not exist, I write it. Some of those are on the special projects page.
- Progress is measured. Scores from day one to end of term, not vibes.
Come and see the room.
In-person classes are at Santisuk English School on Lat Phrao Road in Khlong Chan, Bang Kapi, Bangkok. You can also study fully online or hybrid from anywhere. The fastest way to reach me is LINE.
