С. нужно правильно расставить фразы в диалоге

Hey, Michael! Haven't heard from you for ages! How have you been? What's new? I'm having my exams at the end of this semester and I'm going to take Math, Russian because they are compulsory. I also have chosen to take chemistry and biology because I think they are really important for me due to the fact that I want to become a doctor. And I also consider them very captivating and interesting as they give us so much to learn about us, human beings. I think nothing could be more mysterious than us, people, that's why I chose to study them hard. I actually want to study languages more as they are crucial too but unfortunately I do not simply have the time for that. That's a pity! What subject do you like to study, Mike? I am really looking forward to seeing you who's summer! Hope we'll both do well in our exams! Sincerely, Ann
