Dear Sir/Madam,
I hope this letter finds you well.
I'm Li Hua, a new student taking summer courses at your school. I'm writing to sincerely request your support in dealing with some challenges during my stay.
For one thing, I find it difficult to follow classes since English isn't my mother tongue. For another, I'm unable to borrow books from the library because I find the procedure is unclear.
Therefore, it would be highly appreciated if the Learning Center could provide with me any assistance, such as personal tutoring or necessary guidance.
Yours sincerely,
Li Hua
