SCJD took a while SCWCD took less than two months, I had no exprerience with JSP's or Servlets. I only used the "SCWCD exam study kit" by Deshmukh and Malavia, ISBN: 1-930110-59-6. This is truly the best exam prep. book I have ever red. It's all you need for the SCWCD. I red the book twice, cover to cover, took all three exams on the CD and went through the question on all the three exams.
