Dear Ms. Hoa,

How are things going for you?

I'm writing to express my gratitude for having you as a high school instructor. I'm learning a lot of practical skills from you that are really helpful. I really enjoy practicing my teamwork skills in your class. These days, I have a lot of group projects to complete, so the skills you taught me are really useful. The skills you taught me allowed me to get excellent grades the previous semester. I'm grateful that your class taught me time management techniques as well. I can better organize my coursework and complete it all on time with its assistance. And you have our sincere gratitude for teaching us so many wonderful lessons. I still recall how enjoyable your class was for me. I appreciate you being such an excellent teacher!

I appreciate your constant encouragement and pushing me to reach my goals.

Sincerely,

Hong.
