I am writing this letter to inform you that today's IELTS class was not only very informative but also interesting.
In Today's IELTS class I have learned more things that there are 3 types of letters and how to write letters from the IELTS exam point of view and also from a personal & professional view. You have explained all the points in detail on how to write Informal, Semi-Formal, and Formal letters. How to start and close a letter, what should be written in the main body of the letter having 150-200 words.
From this class I have got to know how to write a letter, I will use this information in the exam & also in professional life.
I am really very grateful to have a wonderful teacher like you.
