Step-by-Step NEET 2018 Question Paper Solutions for Physics, Chemistry & Biology








Step-by-Step Solutions: NEET 2018 Chemistry


NEET 2018 Chemistry section consisted of number of questions from Physical Chemistry, Organic Chemistry and Inorganic Chemistry. Most of the questions directly derived from NCERT concepts.


Example Question – Chemical Equilibrium


Question:
What does a large equilibrium constant signify about a reaction?


Step-by-Step Solution




  • Equilibrium constant (K) [which tells you product to reactant ratio at equilibrium]




  • This tells us that for a large value K, the concentration of product is much more than the concentration of reactant.




  • This means that the reaction goes almost all the way to product formation.




  • The reaction lies far toward product formation.






Example Question – Organic Chemistry


Question:
Which of the following functional group is present in aldehyde?


Step-by-Step Solution




  • Aldehydes contain a carbonyl group.




  • The carbonyl carbon has a single bond to one hydrogen.




  • The typical structure of an aldehyde is –CHO.




Correct Answer: –CHO functional group


NCERT based questions dominated organic chemistry in NEET 2018, which is the reason to read the textbook thoroughly as it produces better understanding.


Students often look at their performance in mock tests and previous papers using a NEET Rank Predictor after completion of the same.




Step-by-Step Solutions: NEET 2018 Biology


Biology (NEET scoring section) — Most of the questions are straight from NCERT based concepts and all require a basic reading level for understanding. Questions based on Botany and Zoology for the NEET 2018 Biology paper.


Example Question – Human Physiology


Question:
What brain part controls voluntary movements?


Step-by-Step Solution




  • The brain consists of several sections such as the cerebrum, cerebellum and brainstem.




  • The cerebrum is responsible for voluntary activities including movement and cognition.




  • The most prominent region of the brain.




Correct Answer: Cerebrum




Example Question – Genetics


Question:
Who is called the father of genetics?


Step-by-Step Solution




  • Citation needed Genetics is the study of heredity and variation.




  • The scientist who first hypothesized the laws of inheritance was Gregor Mendel.




  • His work with pea plants laid the groundwork for genetics.




Correct Answer: Gregor Mendel




Top Biology Chapters in NEET 2018


Biology was more NCERT based and covered a lot of topics like:




  • Human Physiology




  • Genetics and Evolution




  • Plant Physiology




  • Ecology and Environment




  • Cell Biology




  • Reproduction




Most students who have followed NCERT books thoroughly and practiced papers perform well in this section.


Also aspirants calculate with the help of NEET Rank Predictor about their expected score after solving Biology questions.




Why Solve NEET 2018 Papers To Increase Your Score


Benefits of Solving NEET 2018 Question Paper


Better Time Management


Along with that, students learn how to distribute the time among the Physics, Chemistry and Biology sections.


Improved Conceptual Understanding


This EMD focuses on the benefits of analyzing step-by-step solutions for clarification.


Increased Confidence


Practice helps you feel less stressed on exam day and more confident in your studies.


Performance Tracking


Tools such as NEET Rank Predictor help students track their improvement.




Significance of NMC, WHO & WDOMS in Medical Education


The recognition of medical education is also important for NEET aspirants.


NMC (National Medical Commission)


The NMC is responsible for the accreditation of medical education in India and ensures that medical colleges maintain academic rigor.




WHO (World Health Organization)


The WHO is the international organization that sets global benchmarks for healthcare and recognize medical education systems worldwide.




World Directory of Medical Schools (WDOMS)


The WDOMS is a worldwide directory of recognized medical schools. Graduates of schools that are listed in the WDOMS often have more options when it comes to licensing exams internationally.


MBBS GUYS NOTE — The universities must be NMC approved, WHO recognized and WDOMS listed.




How To Use NEET Rank Predictor After Attending Practice Papers


The NEET Rank Predictor helps students analyze their approximate rank based on score in exam.


Benefits include:




  • Predicting expected rank




  • Medical Colleges Chance of Admission




  • Planning counseling strategies




  • Setting realistic preparation goals




NEET Previous Year (2019, 2020) Papers: NEET is a national-level entrance exam; students come from every part of the country and different boards that conduct the examination.




NEET Preparational Guide for Students Aspiring to Future Exams


NEET aspirants looking to enhance their score must adopt a well-defined preparation strategy:




  • Study NCERT textbooks thoroughly.




  • Regularly attempt previous years’ question papers.




  • Take mock tests and simulate exam conditions.




  • Focused on mistakes and attempted weak topics.




  • And check the progress using the NEET Rank Predictor.




Success in NEET requires consistent and disciplined preparation.




Conclusion


NEET 2018 Question Paper: With detailed information regarding the structure, level of difficulty and common topics from Physics, Chemistry and Biology step by step solutions to the paper helps the students in grasping their concepts tighter, enhance time management skills and boost confidence for appearing at the final exam.


Solving previous years’ papers repeatedly helps aspirants to keep the track of their progress and predict their expected rank using NEET Rank Predictor tools.


Hence, alongside all other factors, students also need to factor in the importance of attending a college approved by NMC, WHO, and WDOMS for a globally valid degree.


NEET aspirants who properly interweave regular practice, intelligent tactics and insight from previous papers can markedly bolster their chances of scoring high enough to get into leading medical institutions.
