Knowing the theory of True/False/Can't Tell is necessary but not sufficient. The real challenge is applying it under the extreme time pressure of the UCAT — approximately 29 seconds per question, including reading time for the passage. This lesson provides a complete decision tree for answering TFC questions at speed, strategies for when to flag and move on, and a structured programme for building speed without sacrificing accuracy.
This decision tree should be applied to every TFC question. With practice, it takes 10–15 seconds.
Identify:
Scan the passage for the most distinctive keyword in the statement. When you find it, read the surrounding 1–2 sentences.
If you cannot find any related content in the passage: → Can't Tell (with high confidence). Move on.
| What You Find | Decision |
|---|---|
| Passage says the same thing (or valid paraphrase) | True |
| Passage says the opposite or something incompatible | False |
| Passage says something related but does not confirm or deny | Can't Tell |
| Statement adds causation, generalisation, or extreme language not in passage | Can't Tell |
| Confidence Level | Action |
|---|---|
| High confidence (>80%) | Confirm and move on |
| Moderate confidence (50–80%) | Confirm your best answer and move on — do NOT spend more time |
| Low confidence (<50%) | Select your best guess, flag the question, and move on |
Total target time: 12–20 seconds per TFC question (plus shared passage reading time).
Flagging is one of the most important UCAT skills. The test interface allows you to flag questions for review, and you should use this feature strategically.
| Situation | Why Flag? |
|---|---|
| You cannot find the relevant section of the passage after 10 seconds of scanning | Spending more time is unlikely to help; come back with fresh eyes |
| The question involves complex negation or double negatives | These take longer to decode; other questions may be easier |
| You are torn between two answers (usually True vs Can't Tell) | Come back if you have time; do not agonise now |
| The passage is unusually dense or confusing | Some passages are harder than others; prioritise easier ones first |
| Situation | Why Not? |
|---|---|
| You are only slightly unsure | A moderate-confidence answer is usually correct; confirming it is not worth the flag |
| You have a clear answer but it "feels wrong" | Trust the decision tree over your feelings |
| You have already flagged 5+ questions | Too many flags means you will not have time to review them all |
In a 44-question section, aim to flag no more than 5–8 questions. If you flag more than this:
Work through all 11 passages and 44 questions in order. Apply the decision tree to every question. Make your best choice for each question. Flag any that you are genuinely unsure about (aim for 5–8 flags).
Pace: Approximately 1 minute 40 seconds per passage (including questions).
Return to flagged questions only. You now have fresh eyes and potentially a better sense of the passage from having answered the other questions.
For each flagged question:
Goal: Get TFC answers right without time pressure.
Goal: Begin applying the decision tree under mild time pressure.
