NEET Paper Analysis of Last 10 years for Biology

NEET Exam, conducted by CBSE was introduced in lieu of the various state level and national level medical entrance exams. It will be conducted for admission into MBBS/BDS courses this year as well.

The number of questions and the difficulty level varies for every section. This article provides you an analysis of the Biology section as observed in the question papers of last 10 years.

Biology Trend Analysis for NEET

Candidates must prepare for Biology from the NCERT books. It is advisable to practice as many NEET Question Papers as possible. This acquaints you with the exam pattern for NEET and the type of questions that are asked in the exam. It is imperative to be thorough with basic concepts to score well in this section. You can expect a range of theoretical and application based questions in this section; most of which are directly picked up from the NCERT Textbooks. 

The NEET paper analysis of last 10 years shows that the question paper for Biology has maximum number of questions from Principles of Inheritance and Variation (67 questions). Molecular basis of Inheritance and Morphology of Flowering Plants are also included in the list of important chapters for NEET. Other important topics include Animal KingdomCell, and Human Health and Disease.

Candidates are advised to refer to help books and online practice papers with in depth explanation of basic concepts. They can also prepare for these topics by solving online mock tests. Acquiring good study material is essential to ace the exam.

Percentage Distribution of Questions

Candidates are questioned from chapters and topics studied in class XI and XII. After analyzing the weightage of questions from class XI and XII, it has emerged that questions from class XI have more weightage than Class XII chapters. Therefore, Class XI CBSE syllabus must be the priority of the candidates while preparing for Biology.

Principles of Inheritance and Variation

It is one of the most important topics of Class XII syllabus.The weightage of questions from this chapter has decreased over the years. However, the level of difficulty has increased over the years making it an important chapter. There are various questions from genetic disorders (chromosomal and mendal), mutation, monohybrid and di-hybrid cross, dominance, alleles, linkage and recombination, sex determination and pedigree analysis.

Molecular Basis of Inheritance

This is a topic from Genetics and Evolution which includes topics like transfer of genes and its manifestation in the offspring. The important concepts that candidates must focus on for scoring well in this section are- DNA as a genetic material, Griffith experiment, RNA, Replication, Transcription, Genetic Coding, Translation, Gene Expression, Human Genome Project and DNA Finger Printing.

Morphology of Flowering Plants

Another important topic for NEET from Class XI CBSE syllabus, it is a part of Structural Organization in Plants. As per the paper analysis, questions from this topic are quite easy. Important topics from this section include Inflorescence, Fruit, Root and Leaves, Seed, and Semi-technical description and families.

Animal Kingdom and Cell: Unit of Life

The inference drawn after analyzing previous years’ question papers is that these chapters have similar weightage or number of questions in the Biology section of NEET. Overall, there have been 47 questions from these chapters over a span of 10 years. Since this chapter is from zoology, the questions are of moderate difficulty level. This section requires candidates to memorize the level of organization and classification from Animal Kingdom.

Cell is another important chapter from which candidates can expect several questions. The important topics include: Endoplasmic Reticulum, Golgi Apparatus, Lysosome, Vacuoles, Mitochondria, Plastids, Ribosomes, Cytoskeleton and Nucleus.

Reproduction in Humans and in Flowering Plants

In the past decade, there has not been much variation in the number of questions asked from this section. The important topics from Sexual Reproduction in Flowering Plants are Stamen, Microsporangium, Pollen Grains, Transverse Section of Anther, Stages of Microscope Maturing, Pistil, Mega Sporangium, Pollination, Double Fertilization, Endosperm, Seed, Apomixes and Poly-Embryo.

The important topics from Human Reproduction are Gametogenesis, Menstrual Cycle, Fertilization, Embryonic Development, Parturition and Lactation. The difficulty level of questions range from moderate to difficult. All the diagrams given in NCERT books are extremely important for NEET since most of the questions are based on them. 

Tips and Tricks to learn Biology

  • Attempt as many conceptual questions on those derivations as you can. This will give you a better understanding of the subject.
  • Look for new questions on similar context from previous year’s question papers, sample papers and other model test papers.
  • Always time yourself while solving sample papers as it will help you better manage time during the exam.
  • Solve as many class 12 sample papers you can, but try to solve at least 3-4 completely. Practice past year question papers & model test papers.
  • Time management is a must; take out time for re-creation as well along side preparation.
  • Try and finish all the topics and questions in the NCERT books.CBSE board questions are majorly based on the question in this book only.
