Ross has sent me a check list of books for 1st and 2nd semesters. Each book has a REQ for school required, R for school recommended, and SR for student recommended. Can anybody tell me if the school recommended items are worth purchasing. I'm planning to purchase the REQ and the SR, but if I purchase the R, my total for books alone will be pretty high. If I don't purchase the R, my cost will be cut in half. Any informative inputs are welcome.
