Hope this letter finds you in good health. I am writing to explain my advice regarding your improvement in English at a language school.

First of all, I was so pleased to hear about that you have planned to enroll for English course at a language education institution. However, you have to know about the teaching method such as it is better if they have electronic gadgets in the classroom which can be beneficial for all learners to learn real conversation between each other throughout the world. Also, the number of students should not exceed fifteen in a single class otherwise you may face communication problem with a tutor while studying in a classroom.

To top it all off, according to my point of view, you have to spend at least 30 hours in a week to get better command in such international language. Hope it would be helpful while selecting a language school for an aforesaid purpose. If you need any more advice, just drop me a line.

All the best,
john
