2. I need Past Objective Papers, but I couldn't find any URL through which I can download all previous objects, can you provide any?
3. Should I prepare from specific books or through internet.
4. What should be the scope of the topics to be covered?
5. Suitable and Adequate resources for preparing Subject and Objectives?
