Marks Distribution Between Class 11 and 12 NEET Topics
| Subject | Class XI | Class XII | ||
| Number of questions | Total marks | Number of questions | Total marks | |
| Physics | 19 | 76 | 26 | 104 |
| Chemistry | 16 | 64 | 29 | 116 |

| Haloalkanes | 12 | 3.26 |
Important NEET Topics for Biology
There was a more uniform distribution of questions in Biology. There was no single unit or topic from which more than 6 questions were asked. Hence it would be wrong to deem any one single chapter most important as all are important.
| Chapter | Times Concepts Asked | Percentage Concepts Asked |
| Principles of Inheritance and Variation | 39 | 7.53 |
| Cell – The Unit of Life | 38 | 7.34 |
| Biological Classification | 28 | 5.41 |
| Morphology of Flowering Plants | 28 | 5.41 |

| Environmental Issues | 17 | 3.28 |
| Chemical Coordination and Integration | 16 | 3.09 |
| Digestion and Absorption | 16 | 3.09 |
So, all the chapters mentioned in NEET 2018 Syllabus are important. As per past years’ papers, it can be safely concluded that mechanics (in Physics), organic chemistry (in Chemistry), and Ecology (in Biology) are crucial for NEET 2018.
Also, pay attention to principles of Inheritance and Variation, Cell – The Unit of Life, Morphology of Flowering Plants, Biological Classification, Sexual Reproduction in Flowering Plants; Electrostatics, Ray Optics, Photoelectric Effect and Electromagnetic Waves, Semiconductors and communication System, Rotational Motion; Chemical Bonding and Molecular Structure, p Block Elements, Alkanes, Alkenes, General Organic Chemistry and Alkynes.
