<p>Suggestion: </p>
<p>When you decide which review book you want, look on Amazon and see if you can’t find it “used”. Many are virtually unused and sell for a fraction of the cost of new ones. My daughter bought one for under .50 (plus shipping still turned out under $5.00) instead of paying close to $20.00. The seller described the condition of the book as “very good” - but it looked almost new. Wish we had known to do this much earlier - we would have saved a ton of money.</p>
<p>You also might skip the latest edition to save a bit - there is often little difference between the latest edition and an earlier one. Look at “Formats” and then click on “Show more formats” - in this way, your son/daughter can pick up earlier editions for limited out-of-pocket expense - particularly good if a certain subject needs extra practice.</p>
<p>Good luck.</p>
