There were around 10 drag and drop questions and around 6-7 questions each from Threads and Generics/Collection, around 2-3 on enums , approx 5-6 on fundamentals (classpath, package etc - last chapter of Kathy's book) and 2 questions on Garbage collector. The questions were much simpler than I had though them to be. I spent around 30 hrs preparing for this exam and just used Kathy's book and the mock exam on the CD.
My prime purpose for taking up this
test was because it was a prerequisite for SCBCD (which is my main focus area as of now).
