Passed the exam today-got 56 questions right..There were atleast half a dozen question from design patterns. Need to be thorough with the EL, custom tags and DD syntax. There were 3 drag and drops.
Would like to thank the forum for the materials and suggestions. It was very useful.
I would highly reccommend Head First JSP and Servlets book. Somewhere I read you would get +20% on what you make with the Final Mock Exam in the book and it was true in my case. Need to read the specifications. Did not buy any commerical exam simulators.
