How to effectively prepare for NEET staying at home without coaching?

It is very essential that candidates preparing for NEET without coaching should undergo self-analysis to know what is their potential and where they actually stand, and the best way is to practice mock tests papers available online with solutions on the Vedantu website.  It is highly possible to crack NEET without any costly coaching as it is up to every individual student how much they should prepare for any examination and not only NEET. 


As the NEET exam is going to be really tough they should give a minimum of 4 hours to study daily apart from their regular academic syllabus. Students should practice by solving past years' question papers and any other sample question papers.


NEET (National Eligibility Cum Entrance Test) exam is indeed considered one of the toughest national medical entrance exams in India which can be faced with ample preparation and confidence. The competition is really high and the factor of only limited seats available for admissions in desired colleges makes NEET even tougher.


It is perfectly fine and cool to have a self-study method of preparation for any competitive entrance tests, not only NEET. Remember there are only quite a few success stories of aspiring students who clear their entrance tests absolutely with no coaching at all.


Preparing Revision notes of Biology for NEET Preparation

It is always good to prepare revision notes for any subject in order to help face exams confidently. Write only those points in your notes that you find are forgetful or really important that needs last-minute revision. Add all the miscellaneous points and lines of the NCERT to your notes very carefully. Prepare with all your concepts crystal clear.


Principles of Inheritance and variation

Genetics is the branch of biology that deals with the main principles and mechanisms of inheritance and variation involved in creating offspring. Inheritance is the process by which characters and other features are passed on from parent to the progeny; it is the basis of which we call heredity. Variation is the degree to which progeny differ from their parents although they are from the same genes. It is hence clear that the mother and father provide equal amounts of genetic material to their offspring.

FAQs on Important Notes of Biology for NEET- Principles of Inheritance and Variation

1. What is Inheritance?

Inheritance is a mechanism through which some specific characteristics are passed on from parents to their offsprings. Understandably, principles of inheritance and variation turn out to be a vital part of every life form.

2. What is an Example of a Variation?

Some examples of variation are plant’s leaf variation, camouflage in animals, eye colour, etc. Notably, variations can be observed mostly in every life form, especially if they are multi-celled organisms. 

3. How is Variation Maintained in the Population?

Primarily variation in a population is maintained through genetic crossover or recombination that occurs during meiosis. 

4. What is the main difference between inheritance and variation?

The main difference between the term heredity and variation is that heredity is the mechanism that directly transmits characters, resemblance as well as differences and other features to the offspring from the parents whereas variation in them represents the visible differences shown by individuals within offspring and species. Hence here Heredity is the passing down of particular spectacular characters from one generation to another and Variation is the differences present in characters exhibited by organisms. Understand that the important thing to keep in mind is that inherited traits are directly passed down from parents to children, whereas heritable traits are not necessarily genetic. 

5. What are the effective ways to learn Biology for NEET quickly?

Make sure that you are crystal clear with all concepts in Biology. Because without understanding the fundamentals and basics of Biology it is difficult to proceed further and prepare for NEET exams. Focus on solving past years' question papers or sample question papers available on the Vedantu website and get the hold of marking schemes and time available to complete the paper on time. By practicing it so often you will be able to learn the system of NEET and how it works. Evaluate yourself and know how much more practice you will actually need.

6. Does NEET preparation compulsorily require special coaching?

Any exam on that matter does not require coaching when you are confident in self-preparation. Start preparing by writing revision notes on important points and concepts, prepare using NCERT notes available on the Vedantu website, then work out past year question papers and evaluate yourself. This will highly be helpful to prepare from home and score well without going to coaching centres. Spend quality time to prepare for NEET exams apart from other academics than any other exams as it is very tough to score. 

7. Is it easy to crack and score in the NEET exams?

NEET is definitely a challenging and difficult exam to score but with proper preparation and ample time you put in your effort you can crack it easily. With limited seats available in the desired colleges and lakhs of students attending the exam it is really difficult to get in. It is indeed considered one of the toughest national medical entrance exams in India. However, with the right preparation tips, references, and guidance, a candidate can definitely crack this exam on the first attempt. Students should not feel lazy and instead put in lots of endless efforts and all their available time in order to score well.

8. What is the pattern followed in the NEET exam?

The pattern followed is almost similar to other entrance exams. NEET or National Eligibility Entrance Test is an offline exam that is paper-based and you will have a time duration of 3 hours to complete the paper. A total of 180 MCQs are asked in the NEET exam from subjects Physics, Chemistry, and Biology (Botany & Zoology). Each question carries 4 marks and 1 mark is deducted for every negative answer. Preparation with past year question papers and sample question papers will help you plan your time around completing the paper and understand how the marking scheme is followed.
