Band 8+: The course director of your previous college has invited you to attend a party for new students, and he has also asked you to give a talk about studying overseas. You have an important examination on the same day so you cannot attend the party. Write a letter to the director to apologize and to explain why you cannot attend the event. Suggest another date when you could give your talk.

Dear Mr. Smith,

I am one of your invited students, and I am writing to express my sincere appreciation for your kind invitation to attend the party and for the opportunity to give a talk about studying overseas. However, I will be unable to attend the party.

It is truly an honor to be considered for this event, but I regret to inform you that I will not be available at the scheduled date because of my academic responsibilities; I have a crucial exam that requires full attention and preparation.

I apologize for any inconvenience my absence may cause, and bear in your mind that it was not an easy decision to make. I am disappointed that I will not be able to share my experience and insights with the new students.

I value the given opportunity thus, I would like to suggest another day; I will not have any engagements on the 5TH of February. I appreciate your understanding and flexibility in rescheduling my talk.

Please let me know if my suggested date works for you. If you require further details, please do not hesitate to contact me.

Sincerely,

Ahmed Ali
