NTSE stand by National Talent Search Examinations, NTSE is conducted by the National Council of Educational Research and Training (NCERT) for identifying talented student who want to pursue higher education in Science and social streams.
The test is performed at two stages, i.e. first the examination of talent at the state level and then the examination of talent at the national level. The students who qualify for the State Level Talent Search Examination are eligible to appear for NCERT‘s NTSE Stage II exam.
Other way to understand what is NTSE:
- Exam name – NTSE (National Talent Search Examinations)
- Levels of NTSE exam – NTSE exam is divided in 2 stages the 1^{st} stage is State level conducted by states/UTs, and 2^{nd} stage is national level conducted by NCERT
- Class level – NTSE is the 10th class level examination.
- Exam duration – 2 hours at each level for each paper (MAT and SAT), ie. 240 minutes in all. MAT stands for Mental Aptitude Test and SAT stands for Scholastic aptitude test.
- NTSE scholarship detail
- Scholarship amount for class 11 and 12 – 1200rs per month.
- Scholarship amount for UG and PG – 2000 rs per month.
- Scholarship for PHO –as per UGS norms
Stages of NTSE examination
NTSE is divided into Stage 1 and Stage 2. In both the stages, subjects, and syllabus are the same. But there is a little bit difference between stage 1 and stage 2 and it depends on the pattern and organizing factors.
So it is essential to have a clear understanding of both the tiers. Thereby the students who clear both the stages are offered scholarships and are called NTSE Scholars.
Stage I
Stage 1 is a state level exam conducted by respective state boards in the month of November every year. NTSE Stage 1 is a process through which students are selected state wise.
In the first tier or Stage 1, there is no time gap between MAT and SAT paper. Providing students the liberty to devote less to one subject and devote more time to other subjects.
Eligibility Criteria for Stage-I:
- Only Indian students are eligible to appear in this level.
- The students studying in Class X are eligible for appearing in this test.
- Minimum 60% marks for General Category and 55% for SC, ST and PH category candidates, in their Class IX (last academic year).
- Candidate must be a student in a recognized school in the respective State or Union Territory
Stage II
The second tier is a national level exam and is conducted by NCERT in the month of May in the succeeding year.
NTSE Stage 2 is a selection process wherein best students out of the best are selected across the nation. So, the level of competition is high, hence one must be adequately prepared for it.
In Stage 2, the questions are analytically based and are of higher difficulty level.
Eligibility Criteria for Stage-II:
- Based on Stage I, students recommended by state, are eligible for the Stage-II to be held by NCERT at National level.
- All the students, who secure the minimum required marks at Stage-II, are eligible for the scholarship program. All the eligible students, who wish to appear in the scholarship programme, are required to register for the same. After the scrutiny of the applications, only eligible candidates are allowed to appear in the exam.
Students who are preparing fer NTSE exam should be aware of how to prepare for NTSE exam and what to prepare for NTSE exam to obtain good marks. The NTSE exam will be conducted in two stages, stage 1 (state–level) and Stage 2 (national–lever) to award scholarships to deserving students.
Here, are some usefuland simple NTSE preparation tips to make students ready for the final day. NTSE exam preparation tips include how and what to prepare for the NTSE exam, these NTSE exam preparation tips and tricks are useful for stage I and stage II exams.
- It is a must for all the aspirants to know what are their strong and weak aspects. A proper and accurate preparation strategy can be formed only after that. So, knowing which areas are the weakest section and provide a proper concentrate more on them while preparing for the exam.
- The only method to track your performance is to attempt sample papers or mock test .Solve as many sample papers or mock tests to keep checking your progress. Also helps you in speeding up the calculations. Solve online as well as offline sample papers.
As the NTSE syllabus is based on the NCERT class 9 and 10th syllabus, you can prepare for the NTSE exam along with regular classes.
- Students will have to understand the basic concepts well and know how to implement them to different issues rather than simply mugging the truth. The coveted scholarship will only be gained by the practical use of knowledge. Learning the test habits and syllabus of both levels is important because learners can make a proper plan of study
- When candidates prepare notes to learn formulas. definitions, and equations, NTSE preparation can be very beneficial. Logically, making these equations written will help us understand them quickly. It‘s also a convenient way to carry notes wherever you want rather than dragging the heavy books. You don‘t have to read the entire chapter at the time of the review. just qo through these notes carefully
- Revision is an important part of any method of planning. Students can easily forget important facts without revision. iIt is also advised that the previously studied syllabus be revised before moving to a new section. This will help you to stay connected with the important topics and to stop the last–minute problems
- As applicants have to study for stage 1 of the NTSE along with the syllabus of the 10th board and subsequently for stage 2. they will not have much time to research on a subject that is not known. Applicant should ask a friend or someone who is sufficiently qualified to explain and go on.
- Understanding your strengths and weaknesses is necessary. Eg. if you‘re strong in mathematics and science, but language is average and social science weak, then you can turn your weaknesses into strengths for a good overall score.
- Follow class IX and X NCERT books for preparation for NTSE. Learning the social studies NCERT book for NTSE in detail is essential.
- A lot of sample papers and mock tests must be solved at least three days a week. There are several practice questions & mock tests on this site. Within the stipulated time you will try to solve these papers so that you can increase your speed and learn the parts which take more time.
- Make sure you access minutely what you could do and what it was hard for you to do. Was it the lack of understanding of the subject? Or have you missed the scores due to silly mistake;? Whatever it is, just critically analyze the performance.
- A decent amount of self–study is important for clearing any test. Becoming an NTSE scholar is one of the most basic and important of all the tips. At least 3–4 hours of self learning should be dedicated to solving this competitive examination.
- Solve as many mental ability questions as possible and you won‘t be surprised on the day of the test. Take the help of seniors and teachers from your class. You will also have greater confidence in your speed, subject knowledge, and accuracy with practice.
- Read reference books carefully to train for NTSE. The handbook of R.5.Aggarwal is extremely helpful in planning for the MAT exams. For mocks, you can refer to books and also do rigorous practice of question bank on ACE website.
NTSE is a scientifically developed evaluation system for class X graduates. Based on the principles taught in class, it tests the strengths and weaKnesses of the student In this scholarship review, approximately 300,000 applicants (a largely self–selective group of students) participate each year and 2,000 scholarships are awarded, of which 775 are not reserved. An NTSE scholar has several things to look forward to in high school and beyond from an exciting and wonderful preparation journey besides a significant standout in your curriculum vitae, some of the advantages of being an NTSE scholar are:
- NTSE scholars are awarded by the Central Government to pursue studies in sciences and social sciences up to the doctoral level. The scholarship is awarded up to the postgraduate level in the case of a professional course such as engineering or medicine..
- Being an NTSE scholar produces supreme confidence in the future to crack such competitive exams. Nearly every one of your classmates at llT is a topper or scholar of NTSE. Studying to become a scholar in NTSE is about simply knowing the definitions. Such training would certainly be useful if you take competitive exams such as NEET ,JEE, CLAT, etc.
- If you aspire to opt–out of the country for advanced studies, then as an NTSE scholar, you have an edge over others. To choose whether to apply for MS / MBA. it also acts as a Differentiator. Those who apply for US scholarships receive additional points to qualify for NTSE. NTSE is familiar to universities abroad and gives preference to candidates who have qua lified for the examination.
- Some of India‘s colleges have seats reserved for NTSE schola rs only This prestigious test is your gateway in the future to an excellent university you may surpass college admission tests to gain direct entry to your preferred class.
- Whether applying for jobs or interviews,“NTSE scholar” on the resume is an added advantage. In government jobs as well, an NTSE scholar is given preference. It is helpful to appear for IFS,IA S,IRS,IPS, etc. interviews.
- At the high school level, NTSE scholars can enjoy discounts on course materials and books so they can purchase some very important and expensive books. I f a student is eligible to apply for entry to another school. NTSE scholars will always be chosen.
Students appearing for the exam shouId follow some dos and don‘ts for the exam day
- Reach the examination center 45 minutes before the scheduled time.
- Candidates reaching after 15 minutes of the given time are not allowed to enter the exam hall.
Students need to bring their admit card, photo identity proof, and ball pen to the enter.
- No gadgets are allowed including watches. calculators, etc.
- Focus in time management and maintain your speed accordingly.
Try to attempt all the questions as there is no negative marking.
Before starting NTSE preparation, very first question that arises in aspirant’s mind is, “Which is the best book for NTSE Preparation?” During any competitive exam preparations, students seem attracted towards different reference books to have more study material and knowledge of different topics. We strongly believes that
–“There is no ideal book for NTSE preparations. Some are too easy and some are having too tough content for NTSE preparation.”
Students tend to look for a book that visibly has a lot study material. They do not realize that some books consist of preparation and practice material which is too easy for the students and some books include material which is really difficult. Moreover, some topics included in these books are not even a part of the syllabus. Students believe that solving really difficult questions would leave them well prepared for the exam. They do not realize that spending hours on irrelevant study material is a waste of time. Your study material must match the standards of your exam syllabus.
NTSE Stage I paper is based on state board syllabus, so students must stick to their state board books for the proper preparation. Whereas, NTSE Stage II paper is based on NCERT syllabus, so students should prepare well from their NCERT books.
Best Books For NTSE SAT
Subjects like Maths, Physics, and Chemistry require a lot of practice for which you must solve each and every question given at the back of each chapter. The number of questions in the State board books and NCERT books are not enough for the preparation. So, once you’re done with all the State board and NCERT questions you must look out for practice sheets. These practice sheets give you enough material to practice from.
Best Book For NTSE MAT
Moreover, for the preparation of MAT, State Board and NCERT books do not provide anything. MAT is a quintessential part and requires consistent practice. To prepare for the MAT section, you must understand the verbal and non- verbal concepts first and then you must solve practice sheets to cover as many questions as you can.
When you are done with your school books and practice sheets, you should invest your time on sample papers and previous years’ question papers. This is one of the most effective ways to prepare for NTSE or any competitive exam in general. There’s no point splurging your parents’ money on irrelevant books that do not even help you reach your potential. State board books, NCERT books, and a standard study material is all you need for your NTSE preparation. Deeper understanding of the subjects and consistent practice is the key to ace NTSE.
