Please can anyone kindly correct my grammar. Thanks in advance

Dear Mr Morales

I am afraid that I would not be able to attend your class this week due to the fact that I have to go to in order to take part in an important tennis tournament. If possible, can you kindly give me details of the classwork and homework to be assigned this week, so I can do my schoolwork while I am away. Thanks in advance.
