Quantitative Reasoning is the section most people are wrong about. The maths itself is not hard — it rarely goes beyond Year 8 or 9 arithmetic, percentages and a handful of formulas. What makes QR brutal is the clock. The whole game is doing simple sums under time pressure, reading data fast, and refusing to fall in love with any single question.
What you're actually facing
QR is 36 questions in 26 minutes. That is well under 45 seconds each, and once you allow for reading the harder data sets, your working target is nearer 30 seconds a question. Sections are scored on the 300–900 scale, three of them feed the 900–2700 total, and there is no negative marking. The marks are flat: a fiddly five-step question is worth exactly the same as a one-line percentage. That single fact should reshape how you play the section.
The speed problem, stated honestly
Most people who underperform on QR knew how to do the maths. They simply ran out of time, or spent two minutes wrestling one ugly question while four easy marks sat unanswered at the end. You do not lose QR by getting hard questions wrong; you lose it by never reaching the easy ones. Treat every second as a budget you are spending, and ask of each question whether it is worth what it is costing you right now.
Skip like it's a strategy, not a failure
Because every question is worth one mark, skipping is not giving up — it is portfolio management. On your first pass, take everything that comes quickly and flag anything that needs heavy reading or a long calculation. Then come back to the flagged ones with whatever time remains. This protects you from the trap of sinking your minutes into the two nastiest items in the set. Aim to reach the last question with a few minutes spare, then mop up the flags.
The mental-maths mindset
The on-screen calculator is a backup, not your default. Strong scorers do most of their arithmetic in their head and reach for the calculator only when the numbers genuinely demand it. That sounds intimidating, but it is a trainable habit: you build a small toolkit of fast moves — rounding, estimating, and a reliable way to find any percentage — so that the obvious questions never touch the keypad. The less you click, the fewer mis-clicks you make and the faster you move.
Delay the maths, plan first
Read the question before you stare at the table, then plan the route to the answer before you calculate anything. Decide what the question gives you and what it actually wants, map the steps in your head, and only then pull the numbers and do the sum. Diving into arithmetic before you have a plan is how people compute the right value for the wrong thing — accurate maths, wrong answer.
How this guide fits together
The rest of the QR method breaks into three parts. First, the core fast-maths rules, built around a percentage ladder that lets you find any percentage in your head. Second, calculator discipline: knowing the moments it genuinely beats mental maths, and how to use it without losing time. Third, reading charts and tables at speed, plus rates and the percentage traps that catch people out. Work through them in order and QR stops being a scramble.
