NSEB Syllabus

Since the year 2000, the Scientific Community of India has held the National Standard Examination in Biology (NSEB), which is an Olympiad programme. This test attracts between 20000 and 60000 candidates each year. It is held in collaboration with the Indian Association of Physics Teachers (IAPT) and the Homi Bhabha Centre for Science Education (HBCSE). The NSEB test is part of the NSE (National Standard Examination), which organises national scientific olympiads to promote students, and provide a platform for them to compete in international competitions.

NSEB exams are held once a year to assess students’ scientific knowledge and provide them with the opportunity to compete in International Olympiads. In this article, the complete details of the NSEB 2021-2022 syllabus can be found.

Exam Syllabus for NSEB

The NSEB syllabus is quite similar to the CBSE Class 11 and 12 curricula. Students should have a good understanding of the NSEB syllabus in order to arrange their study plan appropriately. This will aid pupils in achieving high results on the NSEB examinations and qualifying for International Olympiads. The following is a list of chapters and subjects covered in the NSEB curriculum 2021-22:

Frequently Asked Questions on NSEB Syllabus 2021-2022

What are the requirements for taking the National Standard Examination in Biology?

To take the NSEB exam, a student must be an Indian citizen and be in the 12th grade or lower, as the exam is primarily for higher secondary students. Another crucial criteria for NSEB 2021-2022 qualification is that the candidate must not have taken their board test as of November 2021.

What are the topics that will be off-limits on the National Standard Examination in Biology in 2021-2022?

The biology themes from the National Council Of Educational Research and Training (NCERT) textbook are covered in the National Standard Examination in Biology. As of this writing, the IAPT (Indian Association Of Physics Teachers), which conducts the test, has not eliminated any topics from the curriculum, and any revisions will be provided on the IAPT official website, as soon as they become available.

Is the NCERT Biology Syllabus for 11th Grade included in the NSEB Exams?

In previous National Standard Examination In Biology exams, the 12th-grade NCERT syllabus was given higher weight. The 12th CBSE syllabus is essentially a continuation of the 11th-grade elementary course. You’ll need to brush up on your fundamental understanding of the themes covered in the 11th NCERT textbook to fully comprehend the 12th-grade curriculum topics.

What are the best biology books to study for the National Standard Exam in Biology?

The National Council of Educational Research and Training (NCERT) publications cover the most essential themes on which questions in the NSEB exam are based. You may remove your concerns and build a firm foundation on the topic by consulting the NCERT Book for Class 11 and Class 12 Biology. Other books to consider are P.S. Dhami’s Pradeep’s A Text Book of Biology for Class 12, B.P. Pander’s S. Chand’s Biology for Class XII, Trueman’s Elementary Biology for Class 12, and S. Chand’s Together with Biology. All these books will assist you in thinking from a different perspective, allowing you to be prepared for any type of question asked during the National Standard Examination in Biology.

What is the number of questions on the NSEB test question paper?

In the NSEB test question paper, students must attempt a total of 80 questions.
