The Scientific Community of India has been conducting the National Standard Examination in Biology (NSEB), an Olympiad program, since 2000. Every year, between 20,000 and 60,000 candidates take this test. It is organised in association with the Homi Bhabha Centre for Science Education (HBCSE) and the Indian Association of Physics Teachers (IAPT). The National Science Olympiads are held annually by the National Standard Examination (NSSE) to encourage students and provide them a chance to compete internationally. The NSEB test is a component of the NSE (National Standard Examination). National Standard Examination in Biology NSEB Syllabus – Biology
The purpose of the once-yearly NSEB exams is to evaluate students’ scientific knowledge and give them the chance to compete in international Olympiads. The whole syllabus for the NSEB is available in this article.
Exam Syllabus for NSEB
The CBSE Class 11 and 12 curricula and the NSEB syllabus are fairly comparable. The NSEB syllabus should be well understood by students in order to properly organize their study schedule. Students will benefit from this in terms of getting good scores on the NSEB exams and being eligible to compete in international Olympiads. The chapters and topics included in the NSEB curriculum are listed below:

Frequently Asked Questions on NSEB Syllabus
Q1 What prerequisites must one meet in order to sit for the Biology National Standard Examination?
Since the NSEB exam is primarily intended for higher secondary students, those who wish to take it must be citizens of India and be in the 12th grade or below. The applicant must not have taken their board exam by November in order to meet another essential need for NSEB qualification.
Q2 Which subjects will be prohibited from being covered on the National Standard Examination in Biology?
The National Standard Examination in Biology covers the biology themes found in the textbook published by the National Council of Educational Research and Training (NCERT). As of this writing, no topics have been removed from the curriculum by the testing organization, the Indian Association of Physics Teachers (IAPT). Any updates will be posted on the IAPT official website as soon as they are made available.
Q3 Do the NSEB Exams cover the material covered in the 11th grade NCERT Biology syllabus?
Prior National Standard Examination in Biology tests assigned a higher weight to the NCERT syllabus for the 12th grade. The eleventh-grade elementary course is mainly continued in the 12th grade CBSE syllabus. To completely understand the topics presented in the 12th grade curriculum, you will need to review your basic comprehension of the concepts taught in the 11th NCERT textbook.
Q4 Which biology textbooks are the best for preparing for the National Standard Exam in Biology?
The most important themes that form the basis of the questions in the NSEB test are covered in the publications published by the National Council of Educational Research and Training (NCERT). You may put your worries to rest and gain a solid understanding of the subject by perusing the Class 11 and Class 12 Biology NCERT Book. Other texts to take into account include S. Chand’s Together with Biology, B.P. Pander’s S. Chand’s Biology for Class XII, P.S. Dhami’s Pradeep’s A Text Book of Biology for Class 12, and Trueman’s Elementary Biology for Class 12. All of these books will help you approach problems from a different angle, which will help you be ready for any kind of question that may come up in the National Standard Examination in Biology.
Q5 How many questions are there on the NSEB test question paper?
Students are required to attempt a total of 80 questions on the NSEB test question paper.
