Difficult 60-Minute Educational Brain Teasers
Budget: £10 – £20 GBP
I am assembling a 60-minute timed assessment to be used as an educational test, and I need a collection of truly challenging brain teasers. The focus is on difficult material: advanced math problems that demand creative reasoning, paired with logical puzzles that force test-takers to think several steps ahead. Word games are not required this time; depth in mathematics and logic is what matters most.
Please calibrate the difficulty so that high-performing students (upper-secondary to early university level) will find the questions tough yet solvable within the hour if they manage their time well.
Deliverables:
• 20–25 original questions (roughly a 60/40 split between math and logic) formatted for a one-hour test
• A separate, fully worked answer key explaining each solution clearly
• Simple timing instructions so the assessment can be administered online or on paper without ambiguity
Clarity, elegance of wording, and absolute originality are essential. If you have experience designing Olympiad-style items or competitive programming math challenges, let me know in your bid—the sharper the twist in each problem, the better.
Attached is a sample of what you would expect
