5 Grammar Revision Underline the correct words. 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 1) must/might do a lot of revision to make sure I pass as many as I 2) shall/can. These exams are very important because the results 3) could/must decide whether I 4) have to/can go to college or not. So you see, I really 5) have to/could try my best. If I do well, I 6) shall/can choose the college I want and if I don't I 7) might/must have to resit the exams or go to a college far away from home. I 8) needn't/mustn't mess it up. Anyway, after my exams, I would love you to come and stay for a weekend. We 9) could/must catch up with each other and do lots of fun things. 10) Can/Must you come the weekend of the 20th of July? Let me know. 111) may/must go and start revising now. Talk to you soon. Love Christine
