Green Zebra English Course Description

Green Zebra English Course is a free, high intensity course for adults. It's meant for upper intermediate and advanced students (B2-C1 levels) desperately searching for a modern, fun and effective way to learn. Teachers are also welcome to use the materials from the course and the Vocabulary Exercise Book with their students. The course consists of 12 lessons. You are going to get a lesson once a week via email.

Every lesson includes:

  1. an interesting video for you to watch
  2. advanced vocabulary from the video for you to study
  3. interactive flashcards with the vocabulary including pronunciation, images and usage examples
  4. a challenging riddle for you to solve
  5. an inspiring article for you to read
  6. a slang expression, a phrasal verb, and an idiom
  7. one more funny video to relax

Additionally, you'll get a free sample and a 25% discount on the Vocabulary Exercise Book. It will make learning and revising the vocabulary easier and more systematic and provide you with the tools to measure your progress. It will also introduce you to various usages of the new words and help you understand them better through effective exercises. These are real-life advanced expressions from witty talks on various topics, such as education, technology, life, creativity, planet Earth and more.

The tasks are meant for the whole week. It will be perfect if you find a little time to study every day, which is much more effective than trying to push all the knowledge into your head once a week (this doesn't work well). It's okay if completing the tasks takes you more than a week or if you skip some of them, but if you keep studying regularly and put enough effort into it, by the end of the course you'll notice a significant improvement of your English.

It's not just about learning new words and improving your current level of English though. These important things are going to happen, but the main goal of the course is to give you the tools and form the habits that will allow you to keep evolving on your own. It will be easy to keep watching and reading about the things that interest you in English after doing it for 3 months. You'll know where to look, how to learn the vocabulary actively and how to make your activities effective. It's about making English an integral part of your daily life, giving you the opporunity to become really good at it with less effort.

Yes, it's all free. No, it's not a scam. I promise you no spam, no advertising, no bullshit - I hate it too. Just quality stuff. You can also unsubscribe any moment if you want to for some reason. And if you feel that the course deserves paying for, you can get the Vocabulary Exercise Book. Right now just enjoy the course and try to make the most of it!

Still not convinced? Have a sneak peek of an example lesson. Mind that you'll get other materials in your complete lesson and there will be more tasks. This is just to give you an idea of what it's like.
