I used to purchase many IELTS courses, but this one is the most amazing. I can remember new words easily. I can learn anywhere, anytime when I have spare time. Highly recommend, especially for Vietnamese IELTS takers who are being lured by a myriad of low quality IELTS classes!!! I hope that you can update more vocab topics! Thank you so much!

By Yuri Klyova on 1/28/2020

A very massive course, with detailed explanations and logical maps of synonyms. The final section of countless examples is unprecedentedly awesome! Thank you very much Charles!

By Murat Akyol on 1/15/2020

The course was really good for recalling old information. I wrote ten-page word list to repeat. Teacher's explanation and samples are sufficient to comprehend the meaning and usage of the word.

By Reembader on 10/4/2019

I really like this course! It contains good memorable examples and clear explanations. I hope author will expand the course with sentences-examples for synonyms. It will be helpful!

By Tomoko Matsuba on 8/25/2017

Thank you very much Charles! There were many words that I wasn't sure. Your presentation definitely led me to the next level and now I am more confident. I am going to review the vocabulary record and move on to writing preparation. Look forward to utilize those words that I learnt here! Thanks again.

By Akbar Zahiri on 8/1/2017

It was excellent, but it would be fantastic if they had phonetics as they are difficult words to learn and also at the end of the lesson all of them were given in a sample text to learn much better and practical.

By Mohamed Yousif on 5/29/2017

Its really a great course. The course contains a wide range of British vocabularies which is needed in the ielts test but sometimes it has been mixed with American vocabularies. Thanks Charles Cornelius

By Elena Kobzar on 3/24/2017

Everything is great ! Very clear explanations and pronounciation. The only difficult thing is to listen to all the videos because pretty soon it becomes a bit boring.
