43 source-reviewed lessons across Listening, Reading, Writing and Speaking. Write or speak, get a practice band estimate for each criterion, see the exact sentences behind it, and fix the biggest problem first.
Academic and General Training live inside the same course. Every lesson was reviewed against its sources before it reached you, and every skill ends the same way: you do the real task, then you see exactly what to fix.
Listening · 6 lessons
Hear it the way you will on test day
Recorded audio in every listening lesson, so you train your ears, not your reading

How to predict what is coming, spot the distractor, and recover when you miss a word

The question types you will actually meet
Academic passages and a General Training reading module, in one place

A practice band estimate for task response, coherence, vocabulary and grammar

Speaking · Parts 1–3
Practice out loud, with nobody listening
Part 1 familiar topics, Part 2 cue cards for the long turn, Part 3 discussion questions

Timed, like the real test
A practice session
How a writing task works.
One task, one honest read of it, one fix. Then the skill comes back to prove it stuck.
1
Write under the clock
Pick a Task 1 or Task 2 prompt and write it the way you will on test day, with the timer running.
2
Read the feedback
A practice band estimate for each criterion, and the exact sentences it rests on. You see which sentence cost you the point.
3
Do one repair drill
Not a list of twenty things to fix. One drill, aimed at the problem that is costing you the most.
4
Prove it later
The same skill comes back in a new prompt, right before you would forget it. When it holds up somewhere new, it counts.
Honesty
The honest band story.
You will see bands on Lumen. Here is exactly what they are, and what they are not.
EstimatesPractice estimates, not scoresEvery band you see is a practice estimate based on that day's work. It is not a test result, and we never promise a band. Your result depends on your practice and on test day.Human reviewA human checks the hard onesWhen the AI is not sure, it says so, and a trained reviewer looks at your work without seeing the AI's estimate first. If you disagree with a result, you can appeal it.TimingTimed like test dayWriting tasks run against the clock and speaking answers are timed, so the pace of the real test is familiar before you get there.
Two tracks
Academic or General Training?
Both tracks are inside the course, so you prepare in one place whichever one you need.
Academic
For university and professional registration
Who takes it: people applying to study at university, or registering with a professional body
Reading: three long passages from books, journals and magazines
Writing Task 1: describe a chart, graph, table, map or process
Listening and Speaking are the same on both tracks
General Training
For work, migration and training programs
Who takes it: people moving abroad for work or migration, or joining a training program
Reading: shorter everyday texts, from notices to workplace documents
Writing Task 1: a letter, formal, semi-formal or informal
Task 2 is an essay on both tracks
