I chose one to one English classes because I think is the best way to improve a language. If you have some knowledge, practice is very important.
I wanted to improve my fluency. I think the most-enjoyable in the lessons are the exercises that are like games. We did different exercises almost every day. And I think the variety on this is good.
The course let me improve my English in fluency, that was my goal. But additionally it helped me to learn more vocabulary and fix grammar mistakes.I always did classes in the traditional way, so it was new and, of course, totally different from my previous classes.
I found the Skype option very useful because I could do it wherever I was.
