Paulina from Poland


It is marvellous! This repetition of tenses was exactly what I needed! Thank you, Seonaid

Kelly from Peru


I say the idioms naturally, it's very rewarding.

Mikhail from Russia


The course was very helpful for getting to know better the most difficult (and most favourite) topic in English - English articles.

Hi, I'm Seonaid, your teacher


And together with the Perfect English Grammar team, I've helped *tens of millions* of students improve their grammar.

I'm a British native speaker of English. I have a Master's degree (MPhil) from Cambridge University in English and Linguistics and I've been teaching English for 21 years.

I live in London, I've studied French, German, Spanish and Japanese myself and I love learning, culture, books and ideas.

(My name is pronounced "show-na"!)
