我想问一下我这个回信有啥语法错误吗？

Question

Dear Kylie:
I have received your letter. I’m so appreciate there is another way that I can do. First, I confirm that the degree I am currently studying at Capital Normal University is the BSc Chemistry (Education). Besides, I have already know the Duolingo English language test and I confirm that I will take the exam in this month before 22 May. And there is another question, I’d like to know more about the pre-sessional English language classes, such as the class period, the fee and the application requirements, so I can compare which method is better for me to prepare.
I will be very appreciated if you can answer my questions above.
      
Best wishes.

Answer 1

这封信的意思全都写明白了，交流的目的已经达到。
如果地道些的话，前两句去掉，替换为 thank you for your reply. 最后一句替换为 Appreciate your update on my question.
