You can find and refer to NTSE books online. However, it is important to remember that the books listed on this page are older NTSE preparation resources and should not be interpreted as evidence of an active NTSE 2026 examination. The official NCERT NTSE page currently provides examination-related records from earlier cycles, including the 2021 examination, along with scholarship information. Students should check the latest official NCERT announcements before relying on any NTSE examination date, eligibility criterion, syllabus or application information.

For students who want to strengthen their academic foundation, NCERT textbooks for the relevant class remain useful resources. Students can also use concept-based study material, previous examination questions and practice resources where appropriate. Given changes in school curricula over time, always compare older preparation material with the latest applicable NCERT textbooks and curriculum before using it for current-year preparation.

So, here is an interesting alternative. Go for NTSE-oriented study material offered by askIITians as additional practice material where appropriate. It can be used to strengthen concepts and problem-solving skills, but students should cross-check the material against the latest applicable curriculum and any future official NTSE notification before treating it as current NTSE 2026 exam preparation.
