Letter to father about ongoing exam

I hope my letter finds you in the best of health. In your last letter you asked me about my exams. I'm sorry to reply to your letter so late. As you know my exams are going on and I have taken three of them so far. There were a day's or two gap after each exam so could write you earlier. I have just came home after taking my Physics exam and there are three days gap for Chemistry exam. I couldn't attempt my first exam well. Maybe because it was my first experience in any external exam. I don't know what happened to me, I couldn't manage time. I attempted half of the last question. I was so upset on that day. Thanks to mom, she consoled me so well that I soon over come this melancholy and started preparing myself for the next exam. She also guided me how to manage time during an exam - which she often did before. Fortunately, I was successful in managing time and did well during the next two exams and attempted all the questions. I hope I will do the best during the remaining three exam, too. Please keep praying for me.

Thanks.
