test soon and he has written to three of his friends to ask for study advice.Here are their replies:
　　From:Amy
　　To:Danny
　　Hi,Danny,you sound worried.Yes,I‘m going to study all weekend for the test.I start by re-reading all my notes.Then I practice by putting all the key ideas onto flashcards.I also read other books on the subjects I‘m studying,not just the school textbooks.To make sure I really understand everything I‘ve studied,I test myself by having my sister ask me questions.Good luck 0n the test!
　　Amy
　　From:Bill
　　To:Danny
　　Hello,Danny.Are you worried about the test?I study by asking the teacher and other students everything I don‘t understand.1 write down the important information and memorize it by reading it aloud.I also find that I concentrate better by taking a short break in between studying.Why don‘t you come over on Sunday?We can revise our homework together.
　　Bill
　　From:Carla

　　Dear Danny,1 was surprised tO get your email.I pass tests by getting a partner to study with.I always pick someone better than me!I‘ve learned a lot by studying in small groups too.Why don‘t you learn from your mistakes?I do!I study by re-reading all my mistakes and trying to understand what my problem was each time.Callme!
