You attended a training session for student volunteers and agreed to help at an open day. The timetable you have just received assigns you to a session that overlaps with a required class. Write an email to the volunteer coordinator, Mr. Lewis.

In your email, do the following:

• Explain the scheduling conflict clearly.
• Offer an alternative time or duty you can complete.
• Ask what you should do to confirm the revised arrangement.

Write as much as you can, in complete sentences.
