Help write an English short message, urgent! ! !

Dear Ping:

Thank you very much for inviting me to attend the English corner in the city library this Saturday. However, as you know, the final exam of e-commerce is next Tuesday, and I have to prepare for it, so I'm afraid I can't go with you.

Have a good time this Saturday. I hope you will like it.

You are sincere,

Hu Yu
