For adult learners
Hit the band your future depends on.
University, a visa, a registration — when a writing score stands between you and the next step, you need marking you can trust and coaching that's specific. Coach Pen marks to the real rubric and shows you the exact moves that lift each criterion.
Marked to the real criteria
Every response is scored against the actual band descriptors — task response, coherence, lexical range, accuracy — with feedback on your own sentences, not a generic grade.
Bring your own writing
Paste an essay you've already written, or respond to a prompt. Coach Pen works on the words you wrote — it never hands you a model answer to copy.
Drill the criterion that's stuck
Plateaued half a band below your target? See exactly which criterion is holding you back, then train just that one until it moves.
Built for adults
A calm, focused interface — no cartoon mascots or gold stars. Just precise marking and clear coaching for a deadline that matters.
The exams we coach
Mark-only modules calibrated to each test's own scale.
Mark one response. See your score.
