1. When should one feel confident enough that he/she is ready for the exam ? I have somehow got a feeling that you cant be 100% prepared, in terms of learning, for this exam.
2. Do the real exam questions tell you to select more than one answer in case of a multiple choice question? E.g: Select 2 or Select 3
3. Let say there are three answers for a given question. I select 2 correct and 1 incorrect option (checkbox selection). In this case will I be awarded partial marks for the 2 correct options or is that my entire answer would be considered wrong ?
Being the pragmatic guy, I strongly recommend hands-on experience.
Write small example programs to try the different technologies out etc - as children do, learn by playing with things!
If you cannot think of examples etc, then perhaps my (free) electronic book can help you with some inspiration. It contains examples for most of the areas related to the certification.
