Where can I get SASMO past papers?

From SIMCC, which runs SASMO. It gives away some older papers, with answers and solutions, on its learning site, and the entry fee includes access to recent years' papers and answer keys there.

Everyone starts on 15 points. In Section A's 15 multiple-choice questions, a right answer earns 2 points, a wrong one loses 1 and a blank scores 0. Each of Section B's 10 non-routine questions earns 4 points, with nothing taken off. The total is 85.

How long is the SASMO paper?

90 minutes for Grades 1 to 12. The K2 paper is 60 minutes with 15 questions. Each grade sits its own paper.

Which grade should my child sit?

Their school level: Primary 1 to 6 sit Grades 1 to 6, Secondary 1 sits Grade 7 and Secondary 2 sits Grade 8. Secondary 3 and 4 and JC sit Grades 9 to 12.

Should my child guess in Section A?

Only when they can rule out most of the choices. A wrong answer costs a point, so a blind guess loses points on average. Section B takes nothing off, so every question there is worth an answer.

SASMO Past Papers: Where to Find Them and How to Use Them

A note from the parent who built this: I’m prepping my own son for the 2028 Year 7 round across three different boards, and everything on this site gets tested on him before it goes live.

SASMO, the Singapore and Asian Schools Math Olympiad, is run by SIMCC, and the real past papers are SIMCC’s. The good news is that some of them are free, straight from SIMCC, with answers and solutions. This guide covers where the real papers are, how the paper is marked, and how to get the most out of each one.

Where the real papers are

Free older papers. SIMCC puts some past SASMO papers, with answers and solutions, on its learning site.
Recent papers with entry.The SASMO entry fee, for school and private candidates alike, includes access to recent years’ papers and answer keys on the same site. If your child is entered, you already have them.

Papers passed around in tuition groups are copies of these. SIMCC owns them, so the official site is the one to use: it has the answer keys, and you know the paper is complete.

How SASMO is marked

Section	Questions	Right	Wrong	Blank
A	15 multiple choice	+2	−1	0
B	10 non-routine questions	+4	0	0

Everyone starts on 15 points, so the paper is out of 85. It lasts 90 minutes for Grades 1 to 12, and each grade has its own paper. The K2 paper is shorter: 60 minutes and 15 questions.

SIMCC’s syllabus has four strands: arithmetic and statistics; geometry and mensuration; word problems solved by the model method or other methods without algebra; and non-routine problems such as number patterns, divisibility, spatial visualisation, logic and simple cryptarithms.

How to use a past paper

Sit it whole, in 90 minutes. The last questions in each section are hard for everyone. Learning to leave one and come back is part of the skill.
Practise the blank. In Section A a wrong answer costs a point, so a blind guess loses points on average. Guess only when most of the choices can be ruled out. In Section B nothing is taken off, so answer every question.
Score it the SASMO way. Start on 15, then add and take away as the table shows. A child who sees blanks scoring better than guesses learns the rule faster than from being told.
Go through every wrong answer with the solution. Olympiad questions repeat ideas more than numbers. One idea understood, such as working backwards or drawing a model, opens a whole family of questions.
Keep the free papers for later. There are only a few of them. Use them as full timed tests in the last weeks, not as everyday practice.

More papers in the same shape

Once the real papers run out, your child needs more of the same kind of thinking. We write SASMO-style olympiad papersfor Primary 1 to JC 2: 15 multiple-choice questions and 10 typed answers in 90 minutes, marked the SASMO way, with a new paper every time. SIMCC also runs the SMKC, Singapore’s Maths Kangaroo contest, and we have SMKC-style competition papers for Primary 1 to Secondary 4 too, scored the SMKC way. For a secondary student entered for the SMO, there are SMO-style Junior and Senior papers, Round 1 and the Round 2 proofs.

To be clear about what these are: papers we wrote, not SIMCC’s, and we are not connected with SIMCC or SASMO. In Section B your child types a whole number. A free account includes 3 practice tests, and a plan opens unlimited tests and unlocks the answers and worked solutions.
