Decision Making is the section most people leave marks on without realising it. There's no reading-speed bottleneck and no fierce time pressure — just a handful of distinct puzzle types, each with a clean method. Learn one reliable approach per type and DM quietly becomes the section you look forward to.
What the section looks like
You get 35 questions in 37 minutes — a little over a minute each — worth 47 marks, because some questions award more than one mark. There's no negative marking, so a blank is simply a wasted question. The headline point: by UCAT standards the time is generous, which means accuracy, not speed, is what separates a good DM score from a great one.
The question types you'll meet
DM is built from six recurring formats. Syllogisms (logical deductions from a few statements), logical puzzles (work out an arrangement), evaluating arguments (pick the strongest yes/no case), Venn diagrams, probability, and drawing conclusions from a short passage or a chart. Most also use the five-statement 'Yes/No, does this follow?' layout, where you judge each statement independently.
One method per type
The biggest mistake is treating every question as a fresh thinking problem. It isn't. Each type has a fixed, repeatable method — a minimum-overlap Venn for syllogisms, a grid for puzzles, a single relevance rule for arguments. When you've drilled the method, you stop deciding how to solve a question and just execute, which is exactly what frees up the accuracy that wins marks.
The timing attack order
Don't answer in the order the screen gives you. Do the fast, near-guaranteed types first and save the slowest for last. A reliable order is: syllogisms, then strongest argument, then Venn diagrams, then probability, then narrative drawing-conclusions, then data/chart conclusions, and logical puzzles last. Banking the quick marks early means a hard puzzle at the end can never cost you four easy questions you didn't reach.
Use the noteboard, not your head
Every method here is built around getting the information out of your head and onto the laminated noteboard. A quick Venn, a small grid, a jotted 'who is what' — these are faster and far more reliable than trying to hold a logic problem in working memory. The strongest candidates sketch early and almost never re-read the stem.
Why accuracy beats speed here
In Verbal Reasoning the enemy is the clock; in DM the enemy is the careless slip. Because you have time, the marginal mark comes from getting questions right, not from shaving seconds. Treat every question as winnable, apply the method cleanly, and only rush at the very end if a checkpoint tells you to.
Where to go next
From here, work through the three method guides below — syllogisms and logical puzzles, evaluating the strongest argument, and Venn diagrams with probability. Each gives you the single approach for its type and a couple of worked mini-examples, so by the end you have a complete toolkit for the section.
