Dear Kate,
I was glad to get your letter. It feels good to hear from you after such a long time. Sorry, I didn't reply sooner but I've been busy with school.I have my finals in a couple of months, so I study a lot these days.
I will take social studies and history exams because I`m going to enter a law school next year. I hope I will pass them.
What about you? What do you want to become in the future? And when are you going to take your final exams? What university have you chosen for yourself? 
I'm sorry, but I must finish my letter here because I have to study a bit for my tomorrow test.  Hope to hear from you soon! 
Take care.
Love, Alina.
