- Marking against the official criteria, criterion by criterion
- Mock exams with the real timings and mark schemes
- Explanations written for Spanish and English speakers
My job is to make simple what looks difficult. The subjunctive, an argued piece of writing, a speaking test that scares you: there is almost always a way of explaining it that makes it obvious.
I have prepared diplomats, civil-service candidates, and people whose move to a French-speaking country or Erasmus place depended on the result. Those exams change lives, and they are prepared as such.
I have taught one to one for fifteen years. But a private lesson reaches one person at a time: that is why I built DELFOnline.
The AI marks instantly. The method, the criteria and the explanations are mine.
An investment that pays for itself
A traditional language school charges £200+/month. A textbook costs £30 and doesn't correct you. With DELFOnline you pay once and keep your 24/7 AI coach forever.

Sitting the DELF B2 in Spain costs between €180 and €220 depending on the centre. Failing once and re-sitting doubles that bill — and costs six months. At €199 paid once, access costs less than a second attempt.
Indicative fees: each examination centre sets its own. Check yours before registering.
