You have a full time job and are also doing a part time evening course. You now find that you can not continue the course. Write a letter to your tutor. In your letter, - describe the situation - explain why you cannot continue at this time - say what action you would like to take

Dear Mr. Smith, I am writing to inform you that I can no longer continue our classes. Although I am going to attend last two lessons in this month in order not to break you schedule, I intend to quit since the next month. The issue is that, I am overvelmed at work right now, and it is becoming too burdensome for me to combine our course and my job. I am becoming too tired and cannot focus on both work and education. Moreover, I had to sale my car, so I commute by public transport, wich is very time-consuming. Therefore, I barely have enough time to sleep. As you remember, I payed for the full semester in advance, and, according our agreement, the payment is not refundable. However, I hope that you would enter in my position and return at least part of this money. Thank you for your consideration. Yours faithfully, Arthur.
