I have the Sybex Deluxe Sec+ guide which I am reading through (Just started tonight

), I cant get or read the Daril book of such short notice, I test out friday/monday (class test on friday, cert on monday.) I took a pretest yesterday, I got a 70% on my first try, I don't know if that is a passing score or not on COMPTIA, but I am defiantly looking for a higher score.
So how good is the sybex book? I also have a few other books including the Sec+ 2008 In Depth, and the Sec+ Fast Pass, but I want to limit my studying material. suggestions?
