To All Students Everywhere:
We begin each revision with great enthusiasm, which usually begins to fade at the halfway point. The one sure
way we have to revive our motivation is to read the many uplifting students’ comments that we have received.
To show you what we mean, we’ve included a sample of their wonderful comments, for which we are eternally grateful.
