CREST is an online exam, and both levels appear above because most Class 6 candidates will be eligible for the second one — see the Level 2 question below. Students pick a slot between 11 am and 7 pm IST on their chosen date. There is also an optional second practice test on 12 and 13 November 2026, and a free practice test available all year round.

Registration: CREST takes registrations two ways: through a school, which receives the prospectus and forms, or directly from the family online at crestolympiads.com/registration for students whose school does not participate. The fee published for students registering from India is ₹275. A child sitting the exam at home needs a working webcam. CREST publishes no hard cutoff date — its own guidance is to register before November rather than a stated deadline, so this is one of the few papers where the family controls the timing. CREST is not the only body a parent can enter alone: Unified Council accepts direct NSTSE entries, Indian Talent Olympiad runs an individual online route with its own later dates, and Humming Bird registers individual students online at ₹150 a subject. Most bodies register through the school. These four do not have to.

Free — deadline calendar

The deadline is set by your school, not by you

Most parents find the exam date and assume they have until then. The registration window closes long before it, and for some papers it has already started closing. Here is how it actually works.

  • Your school registers your child and your school picks which of the 2–3 dates the class sits. The family does not choose.
  • For SOF papers, registrations must reach SOF exactly 30 days before that chosen date — and once the school has chosen, the date cannot be changed.
  • Most bodies register through the school. Four do not have to: CREST (online, no published cutoff), Unified Council for NSTSE (₹350 direct against ₹150 via school), Indian Talent Olympiad on its individual online route (its own later dates — Slot 1 closes 30 October), and Humming Bird (online, ₹150 a subject, no published cutoff — its two dates are picked as you register). CREST is the simplest of the four.

Exam pattern

How the CMO paper is structured

SectionQuestionsMarks per questionSection total
Section 1 — Practical Mathematics40140
Section 2 — Achievers Section10220
Total50 questions60 marks · 60 minutes

Both sections draw on the same syllabus — the Achievers Section is not extra topics, it is the same fourteen topics asked as higher-order-thinking questions at two marks each. Those ten questions are 20 of the 60 marks, so a third of the paper sits in the harder section.

The thing worth knowing before you open a book: CREST publishes its Class 6 maths syllabus as the contents page of the pre-2023 NCERT, not the book your child is actually studying from. Its fourteen listed topics are Knowing Our Numbers, Whole Numbers, Playing with Numbers, Basic Geometrical Ideas, Understanding Elementary Shapes, Integers, Fractions, Decimals, Data Handling, Mensuration, Algebra, Ratio and Proportion, Symmetry and Practical Geometry. Four of those fourteen have no chapter in the 2026-27 Ganita Prakash at all: Roman numerals (from the old Knowing Our Numbers), ratio and proportion including the unitary method, algebra — both algebraic expressions and simple one-variable equations — and the three-dimensional solids half of Understanding Elementary Shapes. A Class 6 child who revises only Ganita Prakash has prepared for ten of CREST's fourteen topics. The mapping in the table above is ours, not CREST's: it is the only way to read the body's old chapter names against the book on your child's desk.

Frequently asked questions

Yes. CREST accepts individual registrations online for students whose school does not participate, at ₹275 for students registering from India, and a child sitting at home needs a webcam. It is one of four bodies a family can enter without the school — Unified Council takes direct NSTSE entries, Indian Talent Olympiad runs an individual online route, and Humming Bird registers individual students online — but CREST is the simplest of the four, because the whole exam is online and there is no published cutoff date to work backwards from.
