Three pairs of short TMUA-style tests. Three different topics: Logic & Proof; Algebra; Geometry & Graph Transformations. Questions and brief worked solutions.

TMUA is the 91¶¶Òõt of Mathematics for University Admission, required for various Economics/Computer Science/Mathematics undergraduate university courses.

First drafts of questions largely written by Google Gemini and then edited/corrected/quality checked by myself.

Why do these tests come in pairs? Corresponding questions on the paired papers match, at least in broad terms (sometimes extremely closely). This means that students can attempt Paper A, then discuss the answers, then have a go at Paper B, perhaps with renewed insight and confidence. Scope of questions on each paper is deliberately limited. Questions are generally pretty tough (just like the real TMUA).

Comments, suggestions for improvement and corrections are welcome.
