Key findings · NEET 2018
- 1
56% of questions were easy, 2 points above the ten-year average of 54%.
- 2
About 36 questions (20%) needed a calculation, against 21% on average; Physics alone was 58% calculation.
- 3
Biological Classification got the biggest boost: 6 questions against a usual 2.5, followed by Organisms and Populations (6 vs 3.0).
- 4
Chemistry tilted to Class 11: 23 of 45 questions (Class 12 share the lowest in ten years).
- 5
95% of tagged questions tested an idea no earlier paper had asked, the highest of the 9 papers measured, yet 69% came from a topic seen before.
