HAST Abstract Reasoning: The Section That Most Determines Your Selective School Result

16 June 2026  ·  6 min read

Abstract reasoning is the HAST section students find most unfamiliar — and the one where targeted preparation produces the largest improvement. Here is exactly how it works, what patterns appear, and how to train for speed and accuracy under exam pressure.

Why Abstract Reasoning Is the Most Trainable HAST Section

Abstract reasoning is the section of the HAST exam that students consistently find most surprising. Unlike verbal or quantitative reasoning, which have some overlap with school content, abstract reasoning uses purely visual sequences with no language and no numbers — just shapes, patterns, and relationships. Many students sit the section without any preparation and find it disorienting. Yet abstract reasoning is also the most reliably trainable section: the question types follow a finite set of patterns, and students who have been drilled on those patterns can answer most questions quickly and accurately. The difference in performance between a prepared and unprepared student on the abstract reasoning section is often larger than in any other section of the HAST.

The Six Pattern Families

Almost every abstract reasoning question in the HAST — and in similar aptitude tests like the UCAT, ACER, and Ignite selection test — belongs to one or more of six pattern families. Learning to identify which family a pattern belongs to is the first skill to develop:

  • Number: count something across the sequence — number of shapes, sides, dots, lines, or intersections
  • Position: track where an element is located — it may rotate position, move in a fixed direction, or oscillate
  • Size: elements change size in a predictable sequence — large to small, or alternating
  • Colour and shading: fill patterns alternate, rotate, or follow a rule — black, white, grey in sequence
  • Shape type: specific shapes (triangles, circles, arrows) are added, removed, or transformed across frames
  • Rotation: an element rotates by a fixed amount (e.g., 45° or 90°) per frame — clockwise or anticlockwise

How to Approach a Question Under Exam Pressure

The approach that consistently produces the best results under HAST exam conditions is a systematic scan rather than an intuitive guess. When a new abstract reasoning question appears: look at the first and last frames first — the change between them often reveals the dominant pattern. Then check all six families in order (number, position, size, colour, shape, rotation) until you find the rule. This takes practice to do quickly — initially students feel slower when they are systematic, but with repetition the scan becomes automatic and takes less than 10 seconds per question. Students who try to 'see' the pattern by staring at the sequence without a framework are slower and less accurate than students who apply a systematic check.

Multi-Rule Questions: When More Than One Pattern Applies

In harder HAST abstract reasoning questions, two or more pattern families operate simultaneously. For example, a sequence might involve both a rotating element (rotation family) and a changing fill pattern (colour family) — and the correct answer must satisfy both rules. These questions trip up students who identify one rule and assume they are done. The check for multi-rule questions: once you have identified one rule, verify that it fully distinguishes the correct answer from all incorrect options. If two answer options both satisfy your identified rule, there is a second rule you have not found yet. Look for what varies between the two possible answers — that variation reveals the second pattern.

Speed: How to Work Quickly Without Rushing

The HAST abstract reasoning section is time-pressured. Students who cannot identify patterns quickly run out of time, and guessing under pressure reduces accuracy. Two habits build the speed required: first, drill each pattern family in isolation before attempting mixed sets — this builds recognition speed for each type individually. Second, practise under timed conditions from early in the preparation period, not just in the final weeks. Students who only practise untimed questions have typically never experienced the cognitive load of the clock ticking during a pattern they cannot immediately solve. Timed practice also helps students develop the habit of moving on after a fixed time on a question rather than stalling — a question left unanswered is worth the same as a question answered wrong, so pacing matters.

How to Structure Your Practice

A preparation schedule that consistently produces improvement for HAST abstract reasoning:

  • Weeks 1–2: learn the six pattern families one at a time using untimed drills — master each before introducing mixed practice
  • Weeks 3–5: mixed untimed practice across all six families, focusing on the systematic scan approach
  • Weeks 6–8: introduce timed practice sets; target 10 to 12 seconds per question
  • Final 4 weeks: full-length timed sections under realistic exam conditions, followed by review of every error
  • Throughout: keep an error log — categorise every missed question by pattern family to identify persistent weaknesses
