The perception of which year's NEET paper was "toughest" can be subjective and vary among students and experts. Difficulty is often assessed based on factors like the novelty of questions, the depth of conceptual understanding required, the lengthiness of the paper, and the complexity of calculations (especially in Physics and Physical Chemistry). Some years are anecdotally cited more often than others for having particularly challenging sections or overall difficulty. For instance, students and analysts might point to specific years where the Physics section was tougher or Biology had more analytical questions. However, without a standardized objective scale applied across all years by the conducting body, it's largely based on comparative analysis and collective student experience. Actionable Insight: While it might be academically interesting to look at past paper difficulty, it's more productive for aspirants to solve a wide range of previous years' papers. This helps understand the spectrum of difficulty and question patterns, enabling better preparation for future exams, regardless of their perceived toughness.
