Sándor, from Hungary


If I want to be honest, I love Seonaid's explanations because they're absolutely clear and understandable. I have got lots of good marks and I am the one of the best students in my class.

Your logical way to teach is very easy to understand and to remember. Your course is unique in the number of interactive exercises. You did a fantastic job. It was my best investment in learning English. I can pass those tests on which I was previously unsuccessful, practically without errors. Еven my writing skills are improved!!!


Rose, from Puerto Rico


Loved the brief and simple explanations that make easy the learning process and the thoughtful exercises to practice with. :) I have been improving my performance in meetings and presentations! Thanks a lot and keep up with the good work! :)


"I can understand English quite well, but I don’t feel confident about my grammar "

I think there are two reasons why we sometimes don't speak English correctly.

1: There are some grammar points that we don’t understand completely.

2: We haven't practised using the grammar enough.

In this course, we're going to fix both of these problems.
