Welcome to Tier 1–3 — Foundational Challenges
Tier 1–3 challenges are designed to build confidence, clarity, and core reasoning skills.
They are entry-level problems meant for anyone — beginners, learners returning to maths, or people exploring new fields.
What to Expect:
• Straightforward logic and maths
• Clear steps
• No advanced knowledge required
• Focus on reasoning, not memorisation
• Ideal warm-up problems
Examples of Tier 1–3 Tasks:
• Basic algebra & arithmetic
• Unit conversions
• Probability fundamentals
• Simple physics (speed, motion, energy)
• Pattern spotting
• Small logic puzzles
These challenges train the essential thinking tools needed for higher tiers.
Take your time, show your working, and enjoy the process — the Archive begins here.
