Paper 2 exam language and response precision

OCR Paper 2 is an 80-mark, 90-minute examination. It has two sections with different purposes:

• Section A tests knowledge, understanding and application from across Paper 2. Answers may include natural English, bullet points, pseudocode, flowcharts, OCR Exam Reference Language or a high-level language, depending on the question.
• Section B focuses on designing, writing, testing and refining programs. OCR advises spending about 50 minutes on Section A and 40 minutes on Section B.

The question tells you the response form required. If a Section B writing question requires OCR Exam Reference Language or a high-level programming language, natural English will not earn the programming marks. You must be able to read OCR Exam Reference Language because examination algorithms use it, but you do not have to memorise it as a second language for your responses. In these worksheets, Python is your high-level language.

Read the command word and the marks

Command	What a strong response normally does
State / identify / name	Gives a precise fact, item or term.
Describe	Gives characteristics or says what happens.
Explain	Gives a point and develops why or how it matters.
Compare	Links similarities or differences directly.
Evaluate	Considers relevant strengths and limitations, then reaches a supported judgement.
Write / complete an algorithm	Uses the programming form named by the question and expresses the logic precisely.

Marks are a useful checklist. A 1-mark question usually needs one correct point. A 4-mark explanation normally needs more than four disconnected keywords: develop the points and link them to the scenario.

From a vague answer to a marked answer

Question: Explain why binary search is suitable for finding a student ID in a sorted list. [3 marks]

Weak answer: “Binary search is quicker.”

Improved answer: “The list is sorted, so binary search can compare the target with the middle item and discard the half that cannot contain it. Repeating this reduces the number of items still to search.”

The improved answer earns credit because it states the required condition, describes the process and explains the reduction in work. Avoid unsupported words such as “better”, “easier” or “more efficient”.

Precision in a programming response

The next task mirrors a short Section B writing question. The program must calculate a delivery charge:

1. a parcel weighing 2 kg or less costs £3;
2. a heavier parcel costs £5;
3. the selected charge must be returned.

Complete the Python function. Keep the parameter and function name so the checks can supply several weights. Do not print a sentence instead of returning the value.

A reliable checking routine

Before leaving an answer:

1. underline the command word and response form;
2. turn the marks into a reasonable number of distinct requirements;
3. use the names and values from the scenario;
4. for code, trace one normal value and one boundary or unusual value;
5. remove vague claims and check that every explanation includes how, why or a consequence.

Minor syntax slips may not always remove every programming mark, but precise logic and recognisable programming commands are essential.

Review

For the next Paper 2 question you attempt, write three notes before answering: command word, response form, marks. This ten-second habit prevents many avoidable losses.
