NEET 2018 exam will be conducted on May 6, 2018. NEET Biology Syllabus is although not difficult but has a vast syllabus. NEET is a single gateway for admission to MBBS/BDS program offered by any government, private or semi-government institute. Every year nearly 10 Lakh students appear for the entrance exam but only a few Students are able to got the seat because of high completion and a limited number of seats.
Biology syllabus can be covered easily with the help of understanding of the topics, in the relative order of their importance.
If prepared well with a good time management plan you can score up to 90% in the biology section. Many of you are not big fans of plant kingdom unit, as there are plenty of scientific terms that are used in this unit, so the best is to prepare this at last as the percentage weigthage of this unit is only 0.7%, so you can be free of all hassles of technical preparations if you just follow the article closely.

NEET 2018 exam pattern:
Biology syllabus as defined by NEET is divided into two parts, Zoology and Botany. The syllabus of Biology on the whole is quite vast, students often waste their time on preparing for plant anatomy section, which has least weightage.
The important chapters are identified on the basis of the syllabus and the expected number of questions that can be framed on the basis of the details given in the syllabus.
A good score in this section can be easily obtained by allocating time to each of the topics in this section as per the importance level of the topic.
The table will help you in creating a time- table following the importance level of the topic.
|Important topics for NEET 2018||Percentage weightage of important chapters|
|Human Physiology Biological Classification Molecular Basis of Inheritance||12.0%|
|Molecular Basis of Inheritance||8.2%|
|Human Health and Diseases||4.3%|
|Biotechnology: Principles and Processes||3.1%|
|Microbes in Human Welfare||2.7%|
|Strategies for Enhancement of Food Production||1.4%|
Preparation tips for NEET Biology:
- As there are plenty of scientific terms that are used in biology, so to keep it simple, try and relate to the definition instead of mugging the definition.
- Discuss the terms and definitions learned with your friends, this will help you in remembering the definitions better.
- Sketch a diagram daily related to the syllabus defined, as plenty of questions are related to diagrams, so you cannot skip the diagram at any cost.
- A study from the best books and in case of biology 90% of the questions are asked from NCERT books.
- Do regular practices of MCQs from different topics, which will help you, identify your strengths and weaknesses.
- Try to work with the 10-year papers and mock exams for doing good preparation.
- Do a self-check of the answers marked by you, go for comparative study.
- Keep a graph of your score in the various test series worked on by you, this will help you in keeping a track of your performance.
- Keep a metric check of your score in various topics, that will help you in identifying the topics where you need more practice or learning.
In order to get an edge in your final performance in the exam, you must work with some good books. There are books that must be referred to specific topics and books that can be used as MCQ reference manuals.
Just keep one thing in mind, study limited books as too many books can create confusion.

The better you prepare for NEET, better is your score and better placement in the college of your choice. It is important that you follow closely the importance of each topic and prepare accordingly. The time allotted to this section is 90 minutes, giving 45 minutes to each Zoology and Botany section independently.
As per the marking scheme, 4 marks are awarded for every correct answer and 1 mark is deducted for every wrong answer.
