This site is excellent. At the moment I work 3 days a week so learning is not that easy. However I found this site is very entertaining and very complete. I don’t have enough time to cover all subjects. I did the test before and I got 6 band. The lessons you give me in this site are more difficult than the actual academic test I did in September 2016.
Overall, I recommend to all my friends to join this site to improve their English skills.
Thank you.
