Short answer: Core textbooks usually need to be replaced when you switch boards, since each board follows its own syllabus and book list. Some reference and general books can still be used, so compare the new syllabus against your old books before buying.
Get the new school's book list first
Ask the new school or board for the official list of prescribed books for your class. Do not rely on a list from last year or from another school, since lists can change. With the correct list in hand, you can check each book against what you already own.
What usually changes
Textbooks follow the board's own syllabus, order of chapters and style of questions. A mathematics book from one board may cover the same topics as another but in a different order and with different exercises. For languages and social science, the difference is usually bigger.
What can often be reused
- Dictionaries, atlases and general reference books
- Story books and general reading
- Subject books for topics that match the new syllabus after checking the contents
- Stationery and geometry boxes
Compare before selling or giving away old books
Do not sell old books before you are sure they are not needed. Compare the chapter list of the old book against the new syllabus, and keep any book that still matches. Understand the differences between boards in our CBSE, ICSE and state board books guide.
Talk to the school and teachers
The new school can often tell you which books are compulsory and which are optional. Ask whether the school wants a particular publisher, and whether workbooks are needed. A teacher may also tell you which chapters differ most from the previous board, so you can plan extra reading or revision for those topics. Doing this early in the session helps you avoid buying the same book twice, and gives you time to find used copies in good condition instead of paying for everything new.
Saving on the new set
School books for the current session are often available second hand if the edition is right. Check the edition and the publisher against your school's list, and make sure no pages are missing. You can browse second hand books, read the NCERT class-wise guide and sell the old school books that you no longer need.
