Course Description

English grammar is sometimes easy. However, certain topics can be very difficult. This course covers many challenging English grammar topics and teaches everything you need to know about them. You will learn the most difficult English grammar points for students to achieve C1 level or to get a score of 7 or more in an IELTS exam. Many students get stuck at B1 English level due to the complex grammar that is particular to English. They may take several courses at this level and not fully understand all the grammar. BUT NOT AFTER THIS COURSE! :-) This course will finally make these difficult grammar topics, including complex B2 English and C1 English grammar points, clear to you. As a result, you will be able to progress much faster and farther in your understanding of English grammar. You will learn:

  1. All the difficult tenses: (e.g. past continuous, present perfect continuous and past perfect continuous)

  2. Reported speech, reported questions

  3. Relative clauses (defining and non-defining)

  4. Passives (all tenses)

  5. Conditionals (including 2nd and 3rd hybrid)

  6. Causatives


    And many more topics.


    This course is for students who are already at A2 level, and who want to become expert English speakers and writers in English. In this course, there is plenty of opportunity to practice the grammar points to consolidate your new-found knowledge. The grammar points are explained visually as well as verbally to ensure that all students will have no difficulties understanding very challenging grammar topics thereby improving their English speaking, writing, reading and listening.

Instructor Details

Barry Leach M.A.

I've taught in Turkish universities for 20 years in English prep programs and at faculty level. I've taught grammar, IELTS preparation, advanced research strategies, and academic writing skills. I've also taught oral presentation skills to all students -- even the shiest ones. My students regularly outperform students in other classes across all the skills: reading, writing, listening, and speaking. I believe that all students can learn the sills that I teach.

It was bellow my level, I have a Trinity level 10 certificate and my gramar level is C2. Moreover I dislike some of the coments, specialy the ones made about other languages not having somo of the grammar like present perfect continuous, as a native Spanish speaker I assure you we not only have said tense but we have a much more complex grammar than English, just look at our verb conjugations

This is a really great course. You can download the summaries of all the topics and make extra notes while you watch. This saved me a lot of time and I could focus more on the video content than on writing full notes. There were also so many question sheets to download. I recommend this course.

Before I took this course I had trouble understanding things like present perfect simple and continuous, but this course explains the psychology behind a lot of English grammar. As a result, I can now understand the difficult grammar points. They are no longer a mystery to me. The teacher also explains the exceptions to the rules and why they are like this. There are many many exercises for practice too.

I bought this course to review my English language having had the B1 certification for the UK visa a few days after. I passed listening/reading with 49/50 and writing with 50/50! I think that it was really helpful and I founded all the information I needed to refresh some grammar. Thank you!

I learned a lot from this course. thank you for everything.

The course is great. The teacher has spent a lot of time. You can see it easily. Furthermore, the course doesn't explain easy things. That's such a good thing because otherwise, it will be waste of time. Besides, this course improved my skills in some subjects which I already knew and taught new things. Additionally, you can ask what you want because the teacher answers the questions. In addition, there are a lot of exercises in the course. It makes you understand.

The course is very good, it is ordered and comprehensive. The huge plus is a huge amount of after-lecture exercises. I think it will help me. It was not perfect, there were typos (some were misleading) in practice pdfs which made doing exercises and checking anwers harder. That's why i cut a half of the star. I also think that people would benefit more, if there were practice concerning different lectures, not only the current one.

The teacher is good, as well as his approach, and his jokes about Jennifer Aniston! I only cut 0,5 stars to 4,5 because of sound issues that occur sometimes. Crackling sounds. However, the course is really good! Easy to understand. UPD: as of today, June 25th 2021, I've got a response from the teacher to my back in the day feedback on this course, and the response was made by Barry only 8 hours before my visit :) What a legend. He re-recorded all the videos within this course (plus for another one) with a better audio quality. Much appreciated, Sir! I do believe this will improve my educational experience & grammar :) and overall satisfaction. Let's go.
