Помогите пожалуйста срочно письмо надо

Hello! I too am preparing to take my exams. This is not an easy job. Just well have to recite the text that you want to remember. On the day of review takes 2-3 hours. And you learned all of the items? How do you spend time on the teaching of any subject? You're hard to learn so much? And now you tell me anything should advise!
