3. Previous Year Cutoffs

Understanding previous year cutoffs provides crucial insight into the competitive landscape and helps in setting a realistic target score. However, specific previous year cutoff data for the UPSC CBI Assistant Programmer post is not readily available in the public domain. Cutoffs are highly dependent on factors such as the number of vacancies, the difficulty level of the examination, and the total number of candidates appearing.

Please Note: Candidates must verify previous year cutoff trends from the official UPSC website or reliable sources once the official notification is released, if such data is made public.

Safe Target Score: Given the competitive nature of UPSC examinations and the prestige associated with a CBI posting, it is highly recommended to aim for a score significantly above what might be perceived as a minimum cutoff. A safe target score would typically be in the range of 70-75% of the total marks in the Recruitment Test. This provides a comfortable buffer and increases your chances of being shortlisted for the interview stage. Aiming high ensures that even if the paper is unexpectedly easy or the competition is exceptionally stiff, you remain a strong contender. Consistent high performance in mock tests will be vital to achieve this target.
