Last updated September 2026

Our take

Based on the ratings of 10,799 students, a sample of their written reviews and the syllabus, as the course stood in September 2026. No course pays to be reviewed.

This is a pick-and-mix grammar reference more than a course to binge. Derek Smith, a British TEFL trainer, teaches the grammar sections: nouns, articles, tenses, prepositions, punctuation and conditionals, plus a pronunciation block and a separate beginners track meant to be watched in order. TJ Walker's communication material takes over the back half, with sections on phone calls, job interviews, PowerPoint and elevator pitches. The course runs about 44 hours across 710 lectures, but the grammar itself is only a part of that.

Reviewers mostly call the explanations clear, simple and step by step, and several say their confidence in speaking and writing went up. The complaints are small but consistent. One reviewer found the present perfect repeated too often, another wanted more interactive practice, and a three-star reviewer said a few lessons move fast and need more examples. Some of the five-star comments talk about SMART goals and assignments, which shows how much of the content is general communication training rather than grammar. Of 10,799 ratings, 5,800 are five stars and 1,167 are three stars.

With 178,569 students and a 4.3 rating, it has been well tested, and it was updated in September 2026. The sensible way to use it is as a lookup tool: jump to the lesson on whatever is shaky and skip the rest. Complete beginners should start with the dedicated beginners section. Anyone after structured drills and lots of graded exercises will likely need a second resource with more practice built in.

Best forLearners who want to look up one grammar point, like present perfect or prepositions, and watch only that lesson.
Skip it ifYou want heavy drills and graded practice, or a grammar-only course without hours of business speaking.

Pros

  • Short, topic-by-topic lessons let learners jump straight to tenses, prepositions or punctuation
  • Reviewers describe the explanations as simple and step by step, and say speaking confidence improved
  • A separate beginners section is built to be watched in order, start to finish
  • UK and US differences are explained in the lessons, and the course was updated in September 2026

Cons

  • Reviewers want more interactive practice and more examples in some lessons
  • More than half the 32 sections cover speaking and business skills, not grammar
  • Some points repeat, such as present perfect, and a few lessons feel rushed
This course helped me feel more confident while speaking and writing in English.

Course Description

This Udemy course gives you, the English language learner, a complete overview of English grammar.

This course will give you the ability to understand English better and the confidence to speak and write English more fluently.

This English grammar course is taught by two world-renowned communications trainers, TJ Walker and Derek Smith.

Message from Derek Smith:

My name is Derek, I’m a native Brit and a qualified and experienced TEFL/TESOL trainer.

I have been teaching English to adults for over 10 years and look forward to using technology to reach a wider audience.

I have a neutral accent which is clear and easy to understand.

This might not be the longest course on Udemy but I do respect your time.

The lessons are as long as necessary, and as short as possible.

Downloadable PDFs for each lesson will form a valuable resource collection for you.

The course is not designed to be accessed in sequence but takes more of a pick-and-mix approach.

For example, if you need help with prepositions of place, simply go to the prepositions section and look for the lesson on prepositions of place.

Or if you need help with present perfect continuous, go to the tenses and aspects section and check out the lesson on present perfect continuous.

The exception to this is the Beginner’s Section, which is intended to be accessed from start to finish, in order.

Where there are differences between UK and US grammar, these are explained in the lesson.

I encourage you to ask questions if you feel that something has not been fully or clearly explained. You will get an answer and, if necessary, the course material will be updated. Depending on the answer, I will add a new lesson to the course.


Here is a brief summary of the course benefits for you:

  • Native speaker

  • Experienced and qualified teacher

  • Neutral and easy-to-understand accent

  • Lessons structured for easy access

  • Downloadable resources for each lesson

  • No bloated lessons to trick you or waste your time

  • Valid for UK and US English

  • Updates as required by the learners

  • Udemy's 30-day refund policy

How many of your boxes did I tick?

This is the English grammar course you need. I look forward to seeing you on the inside.


Message from TJ Walker

I have been teaching executives around the globe to deliver presentations in English for the last 30 years. Most people, even native English speakers, are insecure about their English grammar. You can become an accomplished speaker and communicator and know that you are using excellent English Grammar every time you speak.

Derek is one of the top English grammar instructors in the world and I am proud to be teaching this course with him. He has the English and European sensibility down perfectly. And I have been living in and working in the United States my entire life. When you put us together, it is a powerful combination designed to help you become a master at English grammar and communication.

Good luck and I hope to see you on the course!

I took this course and found it very excellent and helpful. My biggest challenge was English grammar, but after taking this course, I understand grammar much better. The instructor explained everything in a very clear and detailed way, starting from the basics and gradually moving to more advanced topics. I really appreciate the effort put into this course. The lessons were well organized, easy to follow, and very informative. I learned a lot and gained more confidence in my English skills. Thank you very much to the instructor for this wonderful course. I highly recommend it to anyone who wants to improve their English grammar.

The Complete English Grammar Course – Perfect Your English is a clear and well-structured course that made grammar easy to understand through simple explanations and practical examples. It helped me build confidence step by step and improve both my writing and speaking skills. While the course is very effective overall, adding more interactive practice would make it even better.

provide better experienced knowledge

By AMAR NATH SAINI on 3/11/2026

This exercise helped me understand how to set clear and practical goals using the SMART method. I learned that goals become easier to achieve when they are specific, measurable, and time-bound instead of being vague. It also made me think about how I can apply new skills in my personal and academic life. Committing my goals to someone else showed me the importance of accountability and motivation. Overall, this exercise helped me become more focused and organized about achieving my future goals.

By Priya Gupta on 3/8/2026

Taking this course was a valuable experience for me. The content aligned well with my current goals, and I found the structure clear and easy to follow. The practical examples and hands-on exercises helped me connect theory with real-world applications, which made the learning process engaging. While some topics were challenging at first, the pace of the course allowed me to revisit and strengthen my understanding. Overall, it was a good match for my interests and skill level, and I feel more confident applying what I’ve learned. Would you like me to make this reflection more formal and academic (suitable for a university submission) or more casual and personal (like feedback for an online training platform)?

By Mudit Garg on 3/4/2026

By Aditya Mishra on 2/27/2026
