dont give up man..If you really want the SCJP you can do it...Im in the same boat as you...my first attempt with about 2 months of studying..I totally bombed it
...my second attempt 2 months later...I almost doubled my score...missed by a few questions...plan on going again soon and passing!
..what Im mostly doing now...is going over my notes(from Khalid, Exam Cram, etc), JQPlus, and coding, coding, and coding. good luck!
