Rich from Chemistry Coach

Meet Rich

Built and managed by a real teacher,
not some tech company

"I built Chemistry Coach (Dexter) to make expert tutoring, advice and resources more accessible. Generic A.I. makes mistakes and assumptions that can lead students astray. Dexter has one job.... to teach chemistry.

Every response, every question and every piece of advice is true to my teaching style. A style that has helped thousands of students achieve their grade potential. Crucially Dexter gets to know the student which can have a real impact on learning"

Student Reviews

"In my mocks in 2020, I came out with a D in my chemistry A-level. I just received an A in my 2021 A level resits, having found Rich to support me through it. Rich breaks things down in a way that it is so easy to understand and the live classes are amazing!"
