Помогите пожалуйста! В английском не шарю.

1 I have been learning English for seven years now. 2 But last year I was not working hard enough for English, that's why my marks were not really that good then. 3 As I want to pass my English exam successfully next year, I am going to study harder this term. 4 During my last summer holidays, my parents sent me on a language course to London. 5 It was great and I think I have learned a lot. 6 Before I went to London, I had not enjoyed learning English. 7 But while I was doing the language course, I met lots of young people from all over the world. 8 There I noticed how important it is to speak foreign languages nowadays. 9 Now I have much more fun learning English than I had before the course. 10 At the moment I am revising English grammar. 11 And I have already begun to read the texts in my English textbooks again. 12 I think I will do one unit every week. 13 My exam is on 15 May, so there is not any time to be lost. 14 If I pass my exams successfully, I will start an apprenticeship in September. 15 And after my apprenticeship, maybe I will go back to London to work there for a while. 16 As you can see, I have become a real London fan already.
