I am writing this letter to inform you that today's IELTS class was very informative.
In Today's IELTS class I have gained lots of information on how to write letters from the IELTS exam point of view and also from a personal & professional view. All the points were explained in detail on how to write Informal, Semi-Formal, and Formal letters. How to start and close a letter, and what should be written in the main body of the letter consisting of four paragraphs were explained thoroughly.
From this class, I have learned many small mistakes which I was making earlier while writing different formats of letters.
I am very grateful to have a wonderful teacher like you. I never met a teacher as patient and resourceful as you. You answered all my questions in detail no matter how simple they were.
Thank you very much for conducting an IELTS writing class and hope to see you tomorrow again.
