I am old enough that it will be my first and last Attempt at CSS that too from the pressure of my friends and few CSPs that i know of. Basically i have done MBA and have more than 5 years of Experience in Marketing, Advertising, Media and all the relevant business functions.

So the help required is simple enough:

Following are the optional subjects i think i will be able to go through easily or have some interest in

International Relations
Journalism and Mass comm
International Law
History of USA
Business Administration

Though i have just studied Business Administration but i guess i will be able to pull some score in the subjects above mentioned

My question is regarding the myths of Scoring trends and subject selections and all.. I would like to ask the members about the combo as well as what on earth are these scoring trends how and where to find them.. if those examiner's Remarks are called the trend then i guess most of the people are going low on scores in every subject. So kindly get me wavered off of this confusion..

Before opting any subject go through its syllabus, last 3-5 years papers, marks trends and then make a pros and cons table for comparative analysis.
Also take a look at your domain related subjects like Accounting-Auditing and Mercantile Law but keeping in view your strengths and weaknesses.
