Dear friend,
I was very happy to hear from you! I'm sorry for keeping silence for so long. I was busy up to my eyes with my Biology project.
I'm so happy now to be in the ninth form! I feel myself as an adult! I think it's one of the most important school years in all our school life. This year we have to pass the exam and I hope everyone will have an excellent mark! I should prepare all this year not to have bad results.
That's all for now. I have to go and help my mom. Looking forward to hearing from you ASAP.
With love,
Your name
