National Entrance Screening Test (NEST) is conducted jointly by National Institute of Science Education and Research (NISER), Bhubaneswar and Mumbai University - Department of Atomic Energy Centre for Excellence in Basic Sciences (UM-DAE CEBS), Mumbai.
Energy Centre for Excellence in Basic Sciences (UM-DAE CEBS), Mumbai. The exam is conducted in order to provide admission to candidates in five-year integrated MSc programme in basic sciences (Physics, Chemistry, Biology, and Mathematics) offered at both NISER and UM-DAE CEBS. Seats available at both institutes are as mentioned below:
|Category||Seats at NISER||Seats at CEBS|
Admissions in NISER, Bhubaneswar and UM-DAE CEBS, Mumbai are done on the basis of a candidate’s score in NEST exam. Candidates who have passed Class XII from Science stream are eligible to apply for NEST exam.
NEST 2018 PATTERN:-
NEST is a computer-based test that consists of five sections having multiple choice questions.
First section of NEST 2018 is mandatory for all candidates. Out of the other four sections, candidates need to attempt any three sections. However, the official website states, Candidates are permitted to attempt as many subject–sections as they wish. Only the best three subject–scores along with the score in the general section will be counted for evaluation.
Marking Scheme: In General section there is no negative marking. However, "in the subject sections, for certain questions there will be negative marking for incorrect answers. Some questions may have one or more correct answers for which marks can only be earned by marking all correct answers and no wrong answer," informs the official website.
Syllabus for NEST 2018 General Section: There is no specific syllabus for the General section. The aim is to test candidate's aptitude for a career in science. Questions are designed to test the candidate’s familiarity with (and not a detailed understanding of) major historical milestones in mathematics, physics, chemistry, biology, astronomy, computer science and environment. There will be some questions designed to test the grasp of mathematics up to 10th standard and application capabilities of the same to simple problems.
Some questions in this section aim to test the candidate’s general ability to comprehend qualitative and quantitative aspects of a given scientific passage. This is done by giving a passage on some scientific topic and questions based on the concepts elaborated in the passage will be asked. Some questions may aim to find whether the candidates can interpret graphical and \ or tabular representation of information. Biology: Cell Biology: Cell theory and cells as unit of life.
Basic concepts of biomolecules – Proteins, Carbohydrates, Lipids, Nucleic acids. Tools and techniques of cell studies – use of microscope and calibration (microscopy), elements of microscope. Biomembranes – transport mechanism, cellular respiration. Cell organelles – structure and functions. Discovery and structure of DNA, processes of replication, transcription, genetic code and translation. Principles of the basic techniques in molecular biology. Enzymes– catalysis, kinetics, activation energy, competitive and non– competitive inhibition. Genetics and Evolution: Fundamentals of genetics and evolution.
Evidences and theories of organic evolution. Organization of the heredity material in chromosomes. Equational division. Reduction division. Mitosis and meiosis compared and contrasted. Significance of meiosis. Mendel's laws of inheritance. Discovery of linkage, sex–linked inheritance. Crossing– over, stage at which crossing– over occurs. Neurospora genetics. Mutation – discovery, types of Mutation and Mutations in diploids.
Role of mutations in evolution. Elaboration of Mendel's laws of inheritance. Monohybrid or Dihybrid crosses. Human genetics – human chromosomes, sex–determination, sex–linked inheritance. Ecology: Physical and biological factors in influencing organisms. Food chains, pyramids of numbers and biomass. Biological equilibrium. Interspecific associations. Bio–diversity. Flora and fauna. Basics of microbial systems, Ecosystems. Humans and Environment: Soil, rainfall and temperature with reference to natural resources. Our natural resources – their uses and abuses. Environmental pollution and preventive measures.
Biodiversity and conservation. Biotechnology: Principles of recombinant DNA technology. Applications of biotechnology. Biology of Animal systems: Digestive System – Modes of nutrition. Different vitamin compounds and their deficiencies. Structure of alimentary canal and associated glands, digestive enzymes and gastrointestinal hormones. Absorption of products of digestion, peristalsis, balanced diet. Respiratory System – Gaseous exchange in animals. Structure of respiratory organs, mechanism of breathing, gaseous transport, tissue respiration.
