EXAM TOOLS
The UCAT provides a basic on-screen calculator during the Quantitative Reasoning subtest. Knowing how to use it efficiently, including keyboard shortcuts and memory functions, can save you significant time across 36 questions in 25 minutes. This guide covers everything you need to know about the calculator so it becomes a time-saver rather than a time-waster.
The UCAT on-screen calculator is a basic model that supports addition, subtraction, multiplication, division, square root, percentage, and memory functions. It does not support advanced operations like trigonometry or logarithms, which are not needed for UCAT questions anyway.
You can open the calculator by clicking its icon on the screen during the Quantitative Reasoning subtest. It appears as a floating window that you can move around the screen to avoid blocking the question data. Familiarise yourself with its layout before test day so you do not waste time figuring out where buttons are.
The calculator is only available in the Quantitative Reasoning section. It is not provided for Decision Making or any other subtest. Plan your preparation accordingly and build mental math skills for the subtests where no calculator is available.
Using the mouse to click individual calculator buttons is slow. Instead, use the keyboard number pad to enter digits and operators. The standard keyboard shortcuts apply: the plus, minus, asterisk, and forward-slash keys perform the four basic operations, and the Enter key equals the result.
The Escape key clears the calculator display, and the Backspace or Delete key removes the last digit entered. Learning these shortcuts means you can keep your eyes on the question data while your fingers handle the calculation, saving several seconds per question.
Practise using these keyboard shortcuts during your mock exams. Many students are surprised by how much faster keyboard entry is compared to mouse clicking, but the speed benefit only materialises if you have rehearsed it beforehand.
The calculator memory functions, typically labelled M+, M-, MR, and MC, let you store intermediate results without writing them down. M+ adds the current display value to memory, M- subtracts it, MR recalls the stored value, and MC clears the memory.
Memory functions are particularly useful for multi-step calculations. For example, if you need to add three values and then divide by another, calculate each value, press M+ after each, then press MR to recall the total and perform the division. This avoids re-entering numbers and reduces errors.
A common mistake is forgetting to clear the memory between questions. Always press MC at the start of a new calculation to ensure you are not carrying over a value from the previous question. Building this habit into your routine prevents unexpected errors.
Not every QR question requires the calculator. If the numbers are simple or the answer options are widely spaced, mental math or estimation is faster. Train yourself to glance at the answer options before reaching for the calculator. If you can eliminate three options by rough estimation, there is no need to calculate precisely.
Questions involving straightforward percentage changes, simple ratios, or basic multiplication and division with round numbers can often be solved mentally in less time than it takes to open and use the calculator. Reserve the calculator for questions with awkward numbers or multi-step calculations.
The decision of whether to use the calculator should be instinctive by test day. During your practice, consciously note which questions you solved faster mentally versus with the calculator. Over time you will develop an accurate sense of when the calculator helps and when it hinders.
FREQUENTLY ASKED QUESTIONS
No. The on-screen calculator is only available during the Quantitative Reasoning subtest. It is not provided for Verbal Reasoning, Decision Making, or Situational Judgement. You need to rely on mental math and your noteboard for any calculations in those sections.
No. Personal calculators, phones, watches, and other electronic devices are not permitted at the Pearson VUE test centre. You must use the on-screen calculator provided within the UCAT software. This is why practising with the on-screen calculator before test day is so important.
You can use the number keys (0-9) to enter digits, the plus, minus, asterisk, and forward-slash keys for operations, Enter or equals for the result, Escape to clear, and Backspace to delete the last digit. Using keyboard entry is significantly faster than clicking buttons with the mouse.
The official UCAT practice tests from the UCAT ANZ consortium include the on-screen calculator, so use those to familiarise yourself with its layout and behaviour. You can also practise with the basic calculator app on your computer using only keyboard shortcuts to build the muscle memory you need.
