I took the SCJP6 exam in Feb2011 however , i did not score well and passed with 65% , now i intend to be taking on the exam again to get a good score . I am a working professional and have to look into SCWCD before i try again at SCJP . Since i had somewhere been lacking in my efforts for SCJP i need to practice and score well in SCWCD . In order to score well do i need to buy some books or mock question papers ? In case so, please assist me with the names of books and mock question links. Please keep in mind while answering that i am a working professional so along with my preparation for exam i need to upgrade my skills with technologies like spring , hibernate etc . Can anyone guide me the right way to a perfect score .
