Why "Close Enough" Matters: The Partial Credit Strategy

Most UCAT preparation focuses on getting answers exactly right. This is important, but it misses a crucial insight: in the SJT, the difference between a good score and a great score often comes down to how you handle the questions you are NOT sure about.

The partial credit system means that your strategy for uncertain questions is just as important as your knowledge of ethics. This lesson explains how to exploit partial credit to maximise your band.

The Core Insight: Consistency Over Perfection

Let us revisit the comparison from Lesson 3, but with more realistic scenarios.

Candidate Profile Comparison

Metric	Candidate A	Candidate B	Candidate C
Questions answered exactly right	40	30	25
Questions one position off	5	25	35
Questions two positions off	10	10	9
Questions three positions off	14	4	0
Estimated score (out of ~276)	~186	~218	~223
Likely band	Band 2/3	Band 1/2	Band 1

Scoring estimate: 4 marks for exact, 3 for one off, 2 for two off, 0 for three off, assuming Appropriateness/Importance-style scoring on all questions for illustration.

Candidate C gets the fewest questions exactly right but scores highest. They achieve this by never being catastrophically wrong. Their worst errors are two positions off, while Candidate A has 14 questions where they are maximally wrong.

This is the "close enough" principle in action.

Strategy 1: Eliminate the Extremes When Uncertain

When you are genuinely unsure about a rating, your goal should be to avoid being three positions away from the correct answer. The safest way to do this is to avoid the extreme ratings ("Very appropriate" / "Very inappropriate" or "Very important" / "Not important at all") unless you are confident.

The Risk-Reward Table for Uncertain Ratings

If the correct answer is "Very appropriate" (Position 1):

Your guess	If correct: marks	If wrong and correct is Position 2: marks	If wrong and correct is Position 3: marks	If wrong and correct is Position 4: marks
Very appropriate (1)	4	3	2	0
Appropriate, but not ideal (2)	3	4	3	2
Inappropriate, but not awful (3)	2	3	4	3
Very inappropriate (4)	0	2	3	4

The middle two ratings (Positions 2 and 3) have a maximum downside of 2 marks lost. The extreme ratings (Positions 1 and 4) have a maximum downside of 4 marks lost (earning 0).

When to Use Extreme Ratings

Extreme ratings are appropriate when you have high confidence:

Scenario	Appropriate extreme rating	Why
The action involves reporting a safeguarding concern	Very appropriate	Patient/child safety is always the top priority
The action involves breaching confidentiality without justification	Very inappropriate	This violates a fundamental professional principle
The consideration is about patient safety	Very important	Safety is the highest-priority ethical consideration
The consideration is about personal convenience	Not important at all	Convenience is almost never a valid clinical factor

When to Use Middle Ratings

Scenario	Safer middle rating	Why
You are unsure whether an action is the best possible response or merely acceptable	Appropriate, but not ideal	Limits your downside if it is actually the best or merely okay
You are unsure whether a factor is critical or merely relevant	Important	Limits your downside if it is actually very important or just minor
The scenario is ambiguous and could be interpreted multiple ways	Choose the middle rating closest to your instinct	Ambiguity suggests the answer is probably not at the extreme

Strategy 2: The "Two-Step" Decision Process

For every rating you give, use this two-step process:

Step 1: Which Half of the Scale?

Ask yourself: "Is this action/consideration broadly positive or broadly negative?"

• Broadly positive: Your answer is either Position 1 (Very appropriate/Very important) or Position 2 (Appropriate, but not ideal/Important)
• Broadly negative: Your answer is either Position 3 (Inappropriate, but not awful/Of minor importance) or Position 4 (Very inappropriate/Not important at all)

This first step should take 3–5 seconds. If you can place yourself in the correct half, your maximum distance from the correct answer is 2 (earning at least 2 marks out of 4).

Step 2: How Far Within That Half?

Once you know which half, ask: "Is this at the extreme end or the moderate end?"

• Extreme end: Position 1 or Position 4
• Moderate end: Position 2 or Position 3

If you are confident, go to the extreme. If you are uncertain, stay moderate. This second step should take 2–3 seconds.

The Two-Step Process in Action

Action: "Tell the patient to search for their symptoms on the internet."

Step 1: Is this broadly positive or negative? Negative. Telling a patient to self-diagnose online is not good medical practice.

Step 2: Is it at the extreme end or the moderate end? This action is not just slightly inappropriate — it could genuinely lead to harm (misinformation, anxiety, delay in seeking proper care). Extreme end.

Rating: Very inappropriate (Position 4).

Action: "Suggest the patient raises their concern with the practice manager."
