and one more thing to know:
the important thing is not WHAT answer you give, but HOW you give it. Learn HOW to approach any particular topic, question etc. and align your studies with the HOW. make outlines of EVERY topic that you study and work upon how to improve it. it will help you in all papers.

you can develop your unique approach, but then work on it. but learn HOW and you will know what "WHAT" is missing, which then you can search.
