Tips to Get Success in NEET Exam




National Eligibility cum Entrance Test, popularly known by its acronym NEET, is an annual national-level examination administered by the National Testing Agency (NTA). NEET exam scores are used for admission to MBBS, BDS, AYUSH, and BVSc Colleges. Both government and private colleges set a minimum NEET score to apply for access. Those who have the highest scores get admission. 


In the last NEET exams held in May 2023, nearly 2.3 lakh students took part, while the total available seats were approximately 1.5 lakh. The number of total MBBS seats across all medical colleges in India is just above one lakh.

There is intense competition for medical seats. To stand a chance of securing one of these seats, students invest significant effort and dedicate countless hours to their studies. Reputed NEET coaching institutes like Giraffe Learning help students prepare in a planned and systematic manner. However, many opt for self-study to prepare for this highly challenging exam.

30-Day Customised Study Plan How to Organise Your NEET Preparation Efficiently

Conducted by the NTA or National Testing Agency, an autonomous agency by the Ministry of Human Resource Development, Government of India, NEET is a national-level, one-tier medical entrance test enforced as per the One Nation, One Test policy. Admissions for BDS and MBBS programs in private or government medical colleges across India are solely based on a candidate’s NEET score. This National Eligibility cum Entrance Test (NEET) assesses students’ potential and knowledge for entrance into medical institutes nationwide.

Since NEET is the only medical entrance test that has replaced AIPMT or All India Pre-Medical Test and other state-level examinations, qualifying for the test to fill medical seats is crucial. Budding medical aspirants can live their dream of securing medical seats in the most prestigious medical colleges by taking up NEET, hence its importance. However, the exam is challenging to crack, depending on your preparation. As a Medical aspirant, you must organise your NEET preparation to achieve success in the exam.

The Challenges of Preparing for NEET

NEET preparation is difficult, and as a student, you must organise your NEET preparation and work on it thoroughly to do well in the exam. You must put in a lot of hard work and time to take up the challenges of NEET preparation. They are as follows:

  • Huge Syllabus: The extensive NEET syllabus is one of the most significant hurdles you will face when preparing for the exam. The blended principles of Class 11 and Class 12 may be daunting, but having a focused mind and a solid study plan can help.

  • Exam Stress: Examination stress may complicate things further because of a need for a clear understanding of the exam pattern. Overcome this challenge by practising many mock tests and solving previous years’ question papers.

  • Fierce Competition: Yet another challenge of NEET preparation is huge competition. Every year, the number of contenders and the competitiveness level increase. However, this may not worry you if you work tirelessly and organise your NEET preparation to achieve your goal.

  • Board Examinations: Managing NEET exam preparation and the Class 12th Board examination simultaneously may be difficult. But do not skip putting in hard work and extra effort, as it will pay off in the long run and get you the ideal medical seat.

  • Lack of Family Support: Many candidates need more family support in NEET preparation. Parents may have several problems in life that can lead to misunderstandings and conflicts. Respect their feelings while assuring them that you will try your best to succeed. 

The Benefits of Having a Customised Study Plan

Since seats for NEET are limited compared to the vast pool of students applying, organise your NEET preparation by developing a customised study plan. Create a personalised NEET study plan with specific time frames and goals, including chapters or topics to be studied, proper time allocation to complete them, mock tests, and a reward system for accomplishing targets. Also, make the best use of available resources for NEET exam preparation, like online courses, textbooks, articles, and reference books. Ensure your study environment is conducive to learning, and take breaks to avoid overworking yourself. Some major benefits of having a customised study plan include:

  • It will keep you engaged for an extended period. That’s because you are more likely to interact and retain content focused on your current preparation. Learning is significantly more engaging when you have relevant and personalised content. Since a customised study plan will consider your requirements, aspirations, interests, and potentials, creating a dynamic study environment conducive to your personal growth and NEET achievement.

  • Your customised study plan will motivate you since you will enjoy the learning process and its outcome. You do not require additional push or nudge to get engrossed in your lessons; you are motivated to put your best foot forward and invest significant energy and time into performing.

  • It also helps you learn at your own pace, which will further assist you in working on your strengths and weaknesses individually. And if you are good at studies, your customised study plan will prevent you from slowing down for the sake of others, as is the case in traditional classrooms.

  • Improved NEET performance and better results are other benefits of a customised study plan. When students are more motivated and engaged, they perform better than usual.

Assessing your Strengths and Weaknesses

With competition skyrocketing for NEET, you must do your best to secure admission to the medical college of your dreams. To emerge victorious, you must know about your strengths, which you must refine further, and your weaknesses, which you must overcome. In short, self-analysis is critical. Understanding strengths and weaknesses is crucial to analyse and streamline your NEET preparation, improve performance, and be better grounded. 

Setting Realistic Goals for Your NEET Preparation

Set realistic goals for your NEET preparation to stay motivated throughout the preparation. Ensure your goals are challenging but achievable, and break them into smaller milestones. Achieving these small milestones will offer you a sense of accomplishment.

Creating a Study Schedule

Many aspirants across India work very hard for NEET. Therefore, you need the correct mind map, a perfectly planned study schedule, and hard work to beat the competition. Frame a flexible study schedule that helps you prioritise, set targets, get clarity, and manage time most effectively, and one that you can modify at your convenience, considering your coaching time. If you are a school-going NEET aspirant, create different time slots to solve question banks and MCQs, take notes, coaching modules, online coaching, material reviewing for the day, and organising your timetable for the next day.

Breaking Down the Syllabus into Manageable Chunks

Since the NEET Exam covers an extensive list of topics and subjects, it can be overwhelming to handle everything together. So, break down the syllabus into small, manageable chunks and approach the preparation procedure systematically. Divide each subject or topic into smaller chapters or sub-topics while efficiently allocating specific study time for each section. Know your strengths and weaknesses early on and prioritise topics based on significance and proficiency level.

Prioritising Subjects and Topics

The NEET syllabus covers Chemistry, Biology, and Physics, and to organise your NEET preparation, identify the most significant topics carrying more weight in the examination and those that have appeared frequently in the previous years’ papers. Prioritising important subjects and topics ensures a great foundation and improved chances of performing well in the NEET Exam. 

Allocating Time for Revision and Practice

Regular revision and practising revised topics are imperative for the best scores in the NEET exam. Have a perfectly planned revision strategy where you do not leave things for the last few months; instead, start revisions right from the beginning of your preparation. Since the NEET exam syllabus is enormous, effective revision and practice can improve your retention of the entire syllabus and important topics to a new level. Important steps to include in your NEET revision and practice are making points, taking mock tests, breaking the NEET syllabus into small chains, and revising your self-made short notes.  

Utilising Effective Study Techniques and Resources

To organise your NEET preparation, manage your time efficiently and use productive study resources and techniques that engage your brain actively, assisting you in understanding and remembering study material better. Remember, active learning minimises distractions, keeps your mind focused on tasks, and prevents time wastage.

Tracking your Progress and Making Adjustments

Tracking your progress is the key to maintaining your NEET revision schedule. Besides monitoring your progress, you must recognise and focus more on your weak areas. Record your preparation and adjust if you think something needs to be added. Also, test yourself regularly through quizzes and practice tests to reinforce your understanding of NEET study materials and resources.

Staying Motivated and Managing Stress

Staying motivated and managing stress throughout NEET preparation can help a lot. There will be points during your NEET preparation when you feel low and negatively about cracking the exam. That’s when you must manage stress and have strong reasons to stay motivated. First, surround yourself with the right people who influence your mindset, decisions, and personality. Ensure they have positive perspectives towards life, especially when preparing for goals.

Next, create and stick to a timetable that offers you a sense of self-discipline while motivating you to perform regular practice during NEET preparation. Other ways to stay motivated during NEET preparation include:

  • Finding a focused study spot.

  • Building interest in subjects.

  • Exercising.

  • Reminding yourself about your goals.

A few stress management techniques are:

  • Staying away from social media apps.

  • Avoiding comparisons with peers.

  • Maintaining a healthy sleep cycle.

  • Having a balanced diet.

  • Meditating.

  • Taking short breaks and following a study plan.   

Seeking Guidance and Support from Mentors or Tutors

NEET preparation is difficult, and you require the support and help of teachers, mentors, family, and friends. Join a good NEET coaching centre known for its supportive and qualified faculty to help you with all clarifications and doubts regarding the different subjects. Mentors or experienced teachers who have already taken the NEET examination and performed well can 

  • advise you on different subjects; 

  • Share strategies and tips for taking the NEET exam; 

  • keep you focused and right on track with your preparation and 

  • offer personalised feedback on your progress and performance

Incorporating Breaks and Self-Care into Your Study Plan

Including breaks and self-care in your study plan can improve focus and productivity and prevent procrastination and distractions during NEET preparation. The process involves taking 5-minute breaks between 30 to 45-minute study sessions. 

Reviewing and Adjusting Your Study Plan as Needed

Regularly reviewing and adjusting your study plan as required is crucial to get the most out of it. Try setting aside time every weekend to check progress and accommodate your schedule. Consider the steps that worked and those that didn’t. Evaluating and refining your approach to NEET preparation will improve your revision, manage time effectively, reduce anxiety and stress, and ultimately help you succeed. 

Examples of Customised Study Plans for Different Study Durations

Best examples of customised study plan for different study durations are based on private school students and other contenders. Here, we will have a look at a customised study plan for the study duration of a school student:

  • 5 to 6 am: Wake up and meditate.

  • 6 to 11 a.m.: Study notes and solve MCQs.

  • 11 to 12 a.m: Take a rest.

  • 12 to 3 p.m.: Make homework, study notes, and take assignments.

  • 9 to 10 pm: Dinner break

  • 10 to 11 p.m: Revise everything you have covered during the day.

The Importance of Consistency and Discipline in NEET Preparation

Consistency and discipline are important to achieve great things in life. Combined with both elements, hard work will never disappoint you. Consistency itself is about building discipline. A regular study schedule can reduce anxiety and stress, help you build retention and momentum, and ultimately succeed in the NEET exam. 

  • Resources and Tools to Help You Organise Your NEET Preparation

All-inclusive and reliable resources and tools are the key to strong NEET preparation. These include mock tests and question banks, online platforms and apps, flashcards, mnemonics, time management, and scheduling tools.

  • Success Stories of Students Who Have Used Customised Study Plans

One of the best success stories of students who have used customised study plans is a student who used blended learning, where he worked at his own pace and teachers offered one-to-one support as required. He gained impressive results, with the student outperforming his peers in varied assessments.

Conclusion: The Key to Efficient NEET Preparation
