The UPSC Prelims exam is meant to serve as a screening test only. The marks of Paper 1 are alone considered for making the merit list for this exam. Only those candidates who have qualified the Prelims can write the Mains exam. The marks scored in the Prelim exam is not counted in the final tally of the Mains exam or the Interview.
The number of candidates who qualify the Prelims Exam is about twelve to thirteen times of the total of the approximate number of vacancies that has to be filled in that year in the various Services and Posts.
It is mandatory for the candidate to appear in both the papers of Prelim exam to be qualified for the evaluation purposes. The candidate will be disqualified in case he or she appears in only one paper of the Prelims exam.
There is “Negative Marking” in the Prelims exam. For every wrong answer, 1/3rd of marks allotted for every question will be reduced from the correct tally of score. So candidates need to be extra careful while making wild guesses in the prelim exams.
