"I have taken many English courses. Some of them were focusing on grammar boring conversations with teachers. I always lost interest. When I saw this course, I knew that it was something different. I enjoy every second with you Nab. Thank you for this opportunity to learn English with this easy and most interesting way, that I have never seen.❤ "

"Nab is an excellent teacher. The first time we talked, he well got what my needs were and on them he has built a learning path suitable for me. He is also a smart, fun and well prepared guy and every class turns into a little adventure"

"I would like to recommend this course because I was able to learn many American useful slang words and expressions that are frequently used, in fact now I can understand the movies much better, and so this course works! Nab is a very good teacher and he is always ready to help you if you have any doubt or question therefore the learning is easier. Honestly, I recommend you if you want to improve your vocabulary."

"A brilliant course, which helps me understand the most common American slang words. I heard many of them from the movies or they were already familiar to me. But here you can find out what they mean and when we should use them, and the short clips are especially beneficial. Also, the tests at the end of each part accurately assess what I have learned in that section. I love the way Nab teaches English, it's catchy and fun. It is the obvious one of the best English instructors in the world. I would highly recommend this course to others. Believe me, you won't regret it. Thanks, Nab! I appreciate what you do."

"The course (Slang World) was great! I love the way Nab explains the meaning of the words with videos first so you can guess it before you get a definition. Also there are lots of examples of usage so it won't be another new word in your vocabulary you don't know when and how to use. Videos are short and absolutely not boring, all the words are up-to-date and are among the most important ones. Nab starts with useful phrases like 'What's up', 'No worries' etc, and goes to more complicated ones: adjectives (hot, lit, flakey), verbs (score, hook up) and nouns (dude, grub)."
