The Logical Distinction: False vs. Can't Tell
Consider these two examples. Passage states: 'The hospital opened in 1987.' Question states: 'The hospital has been operational for over 50 years.' Answer: False — because 2026 minus 1987 is 39 years, and the passage directly allows us to calculate this as less than 50. Now a second example. Passage states: 'The hospital opened in 1987.' Question states: 'The hospital is one of the oldest in the city.' Answer: Can't Tell — because the passage gives no information about other hospitals in the city or how old they are. We cannot confirm or deny the relative comparison. The test: to answer False, you must be able to point to a specific piece of passage text that contradicts the statement. To answer Can't Tell, you simply need to identify that the passage does not contain the information required to make a judgment. If the passage is silent on the topic of the question, it is always Can't Tell.
Language Patterns That Signal Each Answer
Certain linguistic patterns in question statements strongly predict which answer is correct, though they are never a substitute for reading carefully. Statements containing superlatives ('the most,' 'the largest,' 'the first') are frequently Can't Tell. Passages rarely make comparative claims that extend to all other possible comparisons. For example, a passage might describe a very successful treatment but never claim it is the most successful treatment ever developed. Statements containing absolute quantifiers ('all,' 'every,' 'never,' 'always') are frequently False. Authors of academic passages avoid absolute claims because they are difficult to defend, so when a question makes an absolute statement, the passage usually provides a counterexample or exception. Statements that directly paraphrase a sentence in the passage are frequently True — but read carefully for subtle changes in wording. UCAT setters often take a passage sentence and alter one word to make the meaning subtly different, turning what looks like a True answer into a False one.

Building the Decision Habit
The goal is to make the True/False/Can't Tell decision automatically, without having to consciously work through the logic each time. Achieving this requires deliberate practice with immediate feedback. For the first week of VR preparation, answer every question slowly and explain your reasoning out loud or in writing: 'I chose Can't Tell because the passage does not mention X.' After one week of this slower, explained practice, switch to timed attempts. You will find the decision process has been internalised. A reliable self-test: when you have chosen an answer, ask 'What would make me wrong?' If you chose True, ask whether there is anything in the passage that contradicts the statement. If you chose False, find the specific passage text that contradicts it. If you cannot find it, reconsider. If you chose Can't Tell, confirm that the passage is genuinely silent on the comparison or detail the question asks about.
