Inside the platform

One teacher. A full coaching platform.Here’s what runs behind every lesson with Isabel.

Every submission lands in a per-criterion grading queue with a 48-hour SLA. Speaking is recorded in your browser, played back in mine, marked across Fluency, Lexical, Grammar and Pronunciation. Writing gets an AI first-pass in seconds, then a human review from me 48 hours later. Your progress shows up as charts, not vibes.

Per-criterion grading

48 hours. Four scores. Margin notes.

Every writing submission is graded across the four official IELTS criteria — Task Response, Coherence & Cohesion, Lexical Resource, Grammatical Range & Accuracy — with margin notes on the actual sentences and a feedback summary that tells you what to fix next. The 48-hour SLA isn’t a promise. It’s a queue with a timer. Overdue submissions are flagged automatically. You’ll never lose a submission to my inbox.

AI first-pass feedback

Two passes. One submission.

The AI reads your essay against the IELTS band descriptors the moment you hit submit and returns an estimated band plus a paragraph of actionable notes — usually inside 30 seconds. Useful when you’ve just finished a draft at 11 p.m. and want a sanity check before bed. It does not replace my review. The AI is fast and unfailingly polite. I’m the one who tells you which sentence is dragging your Lexical band down and what to do about it.

Task Response — you address both views and give a clear position in the introduction.

Pulling the band down

Coherence — body paragraph 2 lacks a topic sentence. Two ideas are running together without a link-back.

Next step: Add an explicit topic sentence to BP2 and re-submit. A human review from Isabel will follow within 48 h.

Speaking practice

Record in your browser. Get marked like the real thing.

Three parts, the same structure as test day. You record each part in your browser — no app, no upload, no Zoom call. I play your audio back inside the grading workspace and mark each part on Fluency & Coherence, Lexical Resource, Grammatical Range & Accuracy, and Pronunciation. You see the four scores plus a written comment per part and a summary across the attempt.Every part is replayable and timestamped — nothing lost to a chat app, nothing graded off a single voice memo.

Full mock exams

All four skills. One sitting. Per-criterion bands in 48 h.

A real mock is reading + writing + listening + speaking, in that order, in one sitting, against the clock. Two hours forty-five minutes. You take it from home. You get back an overall band, a per-skill band, per-criterion sub-scores for writing and speaking, and notes on the leaks that showed up under exam pressure. $99. Once. No subscription, no expiry. Take one a fortnight before your test, then a second one the week of, and watch the band trajectory close.

Progress dashboards

Charts, not vibes.

Your portal shows a band-trajectory line per skill across every attempt, the delta since your first submission, the gap to your target band, and which skill is currently dragging the overall down. If a skill flatlines for three sessions in a row, I’ll see it before you ask. The whole point is that lesson time stops being spent on status updates and starts being spent on the work itself.

The cheat-sheet library

29 guides written from real student notes.

Articles. Conditionals. True / False / Not Given. Speaking Part 3 abstract reasoning. Task 1 chart language. Every leak I’ve seen repeat across hundreds of students, written down once so the lesson hour can be about your writing — not catching you up on the basics every other student already knows. Free to read on the public site. Unlocked the entire time your program is active in the portal — with each guide cross-linked to the relevant practice tests.

Pick the format that fits

Different prep formats fit different people.

Self-paced video courses suit candidates who want to study on their own schedule at low cost. Group classes work well early in your prep when you want a structured curriculum and don’t mind sharing the teacher.

This service is built for the candidate who’s already done some of that, has a target band in mind, and wants direct attention from one teacher with the infrastructure to back it up.
