Bucklix is a revision quiz for the IStructE Certificate in Structural Behaviour (CiSB) — the exam that tests your feel for how structures carry load: supports and reactions, bending and shear, sections, buckling, stability and load paths.
How to play. Each round draws 25 questions from a bank of 200. Pick a difficulty band — Foundations , Frame action or Stability — or leave it on All , tap Start test , choose an answer, then open the Why? for the reasoning. Use ← Prev / Next → to move between questions in a round.
Scoring. A correct answer scores +10, and consecutive correct answers add a streak bonus (up to +10 more). Before answering you can mark Sure or Guessed — a confident miss gets flagged so you revise it first.
Weak-spot focus (in Settings) biases each round toward questions you've gotten wrong or were unsure about. Review mistakes shows every question you've missed as a card — read the answer and reasoning, or tap Test me on these to drill them.
