Each Mock is built as one whole unit just like the real UKCAT test. They are not a random assortment of questions picked from a larger bank of questions. Every Mock is designed with specific questions in a specific order. This is one of the main reasons for flagging harder questions you might face early on in a subtest. These early hard questions trip up a lot of students. This and other features are taken into account when we build our Mocks.
When you go and sit the UKCAT, you will be given one of three pre-prepared UKCAT tests. You cannot know which test you will be given. Each of these UKCAT tests have been specifically made with well-tested questions in a specific order. They have been rigorously tested against a test pool of students before they get released. The scores are then taken from these students to calculate which raw mark correlates to which standardised score between 300 and 900.
A lot of time and effort has been expended to write each Mock. We did not take a random selection of our practice questions and package them up as a Mock. The five-question PRACTICE is used to build strategy and technique over time. Each question set should increase in difficulty so that you get tested on the content. For example, in Quantitative Reasoning on averages, chart and table reading, etc.
The Mocks on the other hand test both your ability to answer the questions but also critically your timing. This is the major benefit of using our Mocks, but also why you must use them carefully.
