Please read it naturally but not too fast.
Hi John,
I was happy to read your letter. Everything is going well now, but I was really busy with my studies at my school. I got a lot of projects to work on, did a lot of homework, and took different tests for a week. I was so happy with my test results because I received high marks on all of them. It could be because I changed the way I studied. I chose to work in groups and got practice every day.
Last week, my mother bought me a new bike as a reward. She was so pleased with my test results. That was the most I could do to make her happy. I hope to get all As in my upcoming exams. Do you want to discuss how to study for exams in our next letters?
Write back soon,
San
Thanks a lot for your kind help.
