How can I speak fluent, polished, confident English?



You're already a high achiever and you want to keep growing and reach your potential in life, but you haven't quite managed to reach your dream level of English yet.


I'd like to suggest that one of the keys to advanced English is a deep understanding of grammar
.


Grammar is more than just a set of rules - it's the backbone of the language and the key to expressing complex ideas clearly and accurately.


Grammar lets you:

  • Speak with precision: Understand the small details that can change the meaning of your sentences.
  • Feel confident: Feel comfortable when you speak and sound professional and polished.
  • Understand sophisticated texts: Fully understand and enjoy high-level texts, from technical documents to novels and poetry.


Advanced grammar isn't just about avoiding mistakes - it's about making your English sound polished, professional and natural. It's the foundation for mastering the English language at a high level.

The Perfect English Grammar Membership


If you're serious about reaching advanced levels of English, you don't have to do it alone.

The Perfect English Grammar Membership is designed to help you develop a deep knowledge of grammar through structured, in-depth courses that guide you step by step.

Why Choose Us?


At Perfect English Grammar, we take grammar seriously because we know it's the foundation for advanced language mastery.

With our logical, carefully structured courses, you'll be in the best possible position to reach the highest levels of English.

Here's how Perfect English Grammar works:



1: In-depth courses. Our courses cover absolutely everything, even very advanced grammar, so that you can see the whole grammar system. It's like having a map of English - everything is clearly laid out for you. And we talk about all the small differences between different grammar structures that aren't usually in English courses. We use clear explanations, short videos, and downloadable PDFs to make sure you really understand everything.


2: Structured learning. Our super-logical lessons are built for your brain and are highly systematic and structured. Each lesson and each course builds on the one before. We start with the foundation and advance logically step by step, so you build a deep, strong understanding of how the language works.


3: Effective practice. We use cognitive science principles, like active recall and interleaving, to make sure that our hundreds of quizzes and exercises are extra effective, leading to a deep knowledge of advanced grammar.


4: Long-term retention. Repetition is the mother of learning! We also base our practice and review structure on cognitive science, using the ideas of spaced repetition and overlearning. This makes sure that you remember (almost!) everything and that you continue to improve.

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.
