Definitely Read all chapters, don't take the shortcut. First, they are not very big chapters, second its your money on the line. YOu should read all three chapters at least twice and do all the quizes here.
Don't be in a hurry to take the test. Test can wait extra two days or a week. You definitely don't want to riskanything. Most likely you will pass with a shortcut but it will be a miracle. My Suggestion Don't try a miracle.
Hope this convince you to do one way or the other
