Answer all the questions! This is the most common mistake of UCAT test takers, as there is no negative marking on this multiple choice test. Each guess you make gives you a chance of getting it right! Remember that each question is worth one mark. Unlike in other exams you have taken, you don't get more marks for questions that are more difficult.
Each question is worth one mark, regardless of difficulty. Thus, if you spend more time on a difficult question, it will be at the expense of other marks on easier questions later in the section.
Memorise your key formulae for Quantitative Reasoning. There are several key formulae that are commonly used in the UCAT Quantitative Reasoning section. Make sure to keep these top of mind, so you can apply them quickly and accurately.
Practice looking for patterns. Get to know the shapes and other elements of patterns that appear time and again on the UCAT. It takes a certain amount of practice to be able to find patterns quickly and accurately, but this is the key to success in Abstract Reasoning.
Practice with test-like material. When taking such a tightly timed test, it is important to get used to the testing format and question types before test day, so you do not waste valuable time figuring out how to use the testing interface.
