Affiliate Disclosure
Last updated September 9, 2026
OlympiadIQ (operated by Guild IT Solutions) is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon (Amazon.in, Amazon.com and other Amazon marketplaces).
As an Amazon Associate, we earn from qualifying purchases.When you click an Amazon link in one of our articles and buy something, we may receive a small commission. This comes out of Amazon's margin — it does not add anything to the price you pay.
How we choose what to recommend
Our recommendations are based on the syllabus fit and teaching value of a book or resource for CBSE and ICSE students preparing for school and Olympiad exams. We link to products we believe are genuinely useful. A commission never buys a place in an article, and we are not paid by any publisher to feature their books.
Prices and availability
Product prices and availability shown on Amazon change over time. Any price and availability information displayed on Amazon at the time you make a purchase is what applies. We do not manually copy prices into our articles; please check the current price on Amazon before buying.
Other links
Some articles also link to free resources (NCERT, exam boards, past papers) and to our own free platform. Those are not affiliate links.
