How it moves a score

This is the same marking and coaching you get on your own writing, shown here on a sample so you can judge it before you sign up.
The two pens: fix and keep
Every mark-up uses two pens (red for what to change, green for what's already working) with a note in plain language. This is a sample sentence, marked the way Coach Pen marks yours.
The storm was very big and the small boat went across the churning, hungry waves as the sailors were scared.
✗ “very big”, “went”, “were scared”: these tell instead of show. Try towering, lurched, and a detail that shows the fear (white-knuckled grip).
✓ “churning, hungry waves”: vivid and personified. Keep doing this.
What one technique changes
Drill a single skill (here, swapping weak verbs and showing instead of telling) and the same idea lands differently.
The storm was very big and the small boat went across the waves as the sailors were scared.
The storm towered overhead as the small boat lurched across the churning, hungry waves, and the sailors' knuckles whitened on the rail.
The writer and the scene stayed the same. The verbs and the details changed, once the technique got drilled in.
The method: markdrillre-mark
Improvement is a loop, run on the criterion holding you back.
Mark
Paste your writing. Coach Pen scores it against the real exam rubric and marks up your own words: red for what to fix, green for what's working.
Drill
The criterion holding your score back links to a short, stepped lesson that trains that skill, one technique at a time, on real examples.
Re-mark
Rewrite and submit again. Watch the same criterion climb, and see the next thing to work on. Repeat until it's automatic.
Marked to the rubric that counts for you
Coach Pen runs the same loop against whichever exam you're aiming at, each on its own real scale.
What learners are saying
Sample — illustrative onlyExample quotes while we gather real stories from learners and families.
“The coaching is on her own writing, not some worksheet. She finally gets why a sentence works — and her openings have completely changed.”
“I'd been stuck on band 6.5 for months. Seeing exactly which criterion was holding me back, then drilling just that, got me to a 7.”
“One technique at a time made it feel doable. He stopped dreading the writing task and started treating it like a game.”
