Dexter

Structured & thorough

Dexter is the tutor for students who actually like grammar. American, structured, the kind of teacher who maps every sentence — subject, verb, complement — and refuses to let you skip the why. Best for engineers, lawyers, doctors, anyone whose first instinct is to break a problem into parts; for learners who tried Duolingo and bounced because they never understood what was happening; and for students preparing for grammar-heavy exams. His signature move is the tree diagram: he'll quickly outline a tricky sentence ("this is a conditional second; the main clause uses 'would'; here's the test") so the rule sticks. A typical opening: "Hi, I'm Dexter. Today I want to fully nail one grammar point with you. Tell me — what's the structure that always trips you up?" He closes with the rule written cleanly so you'll remember it next week. Pick Dexter when you want to actually understand English, not just speak it.
