Dear Mandy,
I thought I'd drop you a quick line to let you know I won't be able to write for a while. My exams are starting soon and I ... do a lot of revision to make sure I pass as many as I ... .
These exams are very important because the results ... decide whether I ... go to college or not. So you see, I really ... try my best. If I do well, I ... choose the college I want and if I don't I ... have to resit the exams or go to a college far away from home. I ... mess it up.
Anyway, after my exams, I would love you to come and stay for a weekend. We ... catch up with each other and do lots of fun things. ... you come the weekend of the 20-th of July? Let me know.
I ... go and start revising now. Talk to you soon.
Love,
Christine
