Introducing the Perfect English Grammar Membership!


A structured grammar program from beginner to advanced level.

One monthly subscription gives you access to everything.

A1: It's time to make the basics automatic!

You'll learn absolutely all the A1 (beginners) grammar, including:

  • How to form questions easily and without thinking so that you can sound really natural.
  • How to use 'will' and 'going to' properly and the situations when it sounds really, really unnatural to use 'going to'.
  • How to avoid basic mistakes with prepositions (like 'go to home' or 'arrive to the airport - these are both wrong!).
  • How native speakers use 'can' and 'could' and 'would' to be polite and how to choose which one to use.
  • The real difference between 'well' and 'good' in modern English and when to use each one.

A2: Master all the parts that no-one really studies but are super useful!

You'll learn absolutely all the A2 (pre-intermediate) grammar, including:

  • How native speakers use 'will' to talk about promises and offers and how you can use it too to sound really natural.
  • How to use the present perfect with 'been' and 'gone' and how the meaning changes depending on which one you choose.
  • When to use the gerund and when to use the infinitive after verbs (we explain it really clearly).
  • The real difference between 'some' and 'any' and the exceptions.
  • How to use 'for', 'while', 'during', 'by', 'until' and lots of other tricky prepositions.

B1: Beyond the basics!

You'll learn absolutely all the B1 (intermediate) grammar, including:

  • How native English speakers use the past continuous tense to make excuses and how you can use it too to sound really natural.
  • How to use the past tense with 'wish' and how it's different from using 'would'.
  • The difference between the present perfect and the past simple (we explain it really clearly).
  • How to use reported speech properly and when exactly you need to backshift the verb tense.
  • How to use modal verbs to be polite - for example the difference between 'can' and 'could' when you're making a request.

B2: Mastery of most grammar - this is getting serious!

You'll learn absolutely all the B2 (upper-intermediate) grammar, including:

  • How native English speakers use the future continuous tense to be polite and how you can use it too to sound really natural.
  • The difference between the present perfect and the present perfect continuous (we explain it really clearly).
  • How to use the causative with 'have' and 'get' (for example 'I had my hair cut' and 'I got may hair cut' and the difference between them.
  • Advanced uses of modal verbs - for example how we use 'will' and 'would' to talk about habits and people's characters.
  • Third and mixed conditionals - like the difference between 'if I had gone to bed early, I wouldn't have been tired' and 'if I had gone to bed early, I wouldn't be tired'.

C1: All the little details for elegant, advanced-level English

You'll learn absolutely all the C1 (advanced) and some C2 (native-level) grammar, including:

  • How native English speakers use cleft sentences in every conversation and how you can use them too to sound much more natural and fluent.
  • Which stative verbs can be used dynamically (it's not all of them) and the situations where using a stative verb dynamically can subtly change the meaning (and when it's just incorrect).
  • How to use the subjunctive in English (yes, we have one!) and when you should absolutely not use it.
  • How to use advanced grammar to be polite in English and how to avoid people misunderstanding you.
  • How native English speakers use tenses to remove emotion from sentences (yes, we're British!) and how you can navigate tricky situations in English by using the same techniques.

Hi, I'm Seonaid!

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 with distinction in English and Linguistics and I've been teaching English for more than 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"!)

Why choose the membership?

  • 1: Complete grammar program with everything in one place

    The courses cover all the English grammar, starting from the beginning and going all the way to a seriously advanced level. It's a complete step-by-step system with absolutely everything you need to improve your grammar.

  • 2: Structured, logical, systematic, organised

    We've spent a long time developing the structure of the lessons inside the PEG membership. They're extremely logical, systematic and organised. It will all make sense to you!

  • 3: Follow the plan and see your progress

    With the PEG membership, you don't need to think about what to study next. You just log in and follow the steps. It's really straightforward and you can see your progress in the progress bar every day.

  • 4: Very, very, very clear explanations

    We're famous for breaking the grammar down into short, clear lessons that are really easy to understand. We talk about all the details, including grammar that isn't in most books. Our students love our way of explaining things!

  • 5: All the way to advanced level

    It can be hard to find courses and materials once you're past intermediate level. We go all the way up to C1 (with some C2 grammar). Perfect if you want to pass an advanced exam or get closer to native-level understanding.

  • 6: Lots and lots of practice

    We all know that repetition is necessary for real learning. Our structured and interactive review exercises and flashcards give you all the practice you need.

  • 7: Reliable information

    We know there's so much on the internet that's not correct! Seonaid has a master's degree with distinction from the University of Cambridge in English and Applied Linguistics and over twenty years of teaching experience. And everyone on the Perfect English Grammar team is a qualified teacher and a native English speaker with a language degree. We really care about providing the highest quality materials possible.

  • 8: Convenience

    Do the lessons whenever you have time and wherever you are. We recommend 20 minutes per day, but we know it's not always possible. We don't promise magic (because languages do need work!) but you can still make good progress with one hour per week.

  • 9: Love!

    We put a lot of love into Perfect English Grammar! We're a tiny company (there are just three of us), we're based in London, and we really care about our students. We'll answer all your questions and we're always here to help you.
