It was my first time participating in the English course. I learned the usage of the word “at.” This is very interesting. The materials give me the examples and also shows me how to use “at” in sentences. So I could quickly understand and apply them.
This is something that is not easy to learn in other English courses. It helped me clarify the definition of “at.”
I feel more confident to use “at.” I recommend this course to all my friends who need to learn English. Thank you Paula and Grace, you are the best.
