The best way to approach the emerging development is to have a broad approach towards General Studies preparation.
As it is designed, with Preliminary Examination, the principle aim of UPSC is to eliminate non-serious and average candidates from the scene. To counter the smart work by some candidates who tried to master preliminary examination, pattern of questions being asked has become more logical and analytical. Moreover, no set blueprint is emerging as far as marks distribution is concerned from the past few years’ papers to establish which specific area of the syllabus is contributing how much?
The best way to approach the emerging development is to have a broad approach towards General Studies preparation. Nothing except the exhaustive study is going to help you as you can’t make an honest attempt till the time you don’t prepare even General Studies from Mains Examination prospective.
It can prove to be suicidal if you ignore any specific area during preparation as each and every section of the syllabus demands proper attention and outstanding preparation. Many a times, it has been observed that candidates take General Mental Ability (GMA) lightly.
To have an edge, you should prepare and practice well for General Mental Ability section as this section continues to get almost similar treatment every year. However, the main deciding factor is your preparation for current events as now more and more questions are framed with recent developments and evolving issues in sight.
Conceptual clarity and clear understanding of the issues and your ability to apply them in broad contexts is all examiners expects from you.
You have to attempt 150 questions in 120 minutes which requires speed and accuracy while attempting questions. So, apart from study, you need to make yourself mentally prepared to face the Prelims which involve stress management and time management techniques.
