Tom Tells You That He Has a History Exam Coming

Tom tells you that he has a history exam coming up in 5 days,and he has 5 chapters to read before the exam.He says he's going to wait and read them all the day before the exam,even if he has to stay up all night,so the material will be fresh in his mind.What advice should you give Tom,and why?

A) That sounds like a great plan,but be sure to take notes on what you're reading so you'll remember it for the test.
B) Read the chapters as soon as possible,taking notes,and go over the notes every day before the exam.This is because every night you sleep after learning information,the more apt you are to remember the information for the exam.
C) Borrow notes from someone else and study them for the first four days,then get up extra early on the morning of the exam,read the five chapters,and don't sleep again until after the exam,because sleeping after you learn something erases most of what you learned.
D) It's too late to try to learn the information in the textbook.Ask the instructor if you can take a later make-up exam.
