How to Tackle HKDSE Paper 1B Python Questions

Why Paper 1B Feels Impossible

Paper 1B carries 35 marks on a single extended programming task. Students often freeze because the question looks overwhelming. The secret: never try to code the whole thing at once.

The 5-Step Breakdown Method

Step 1: Read the Question Twice (2 minutes)

First read: understand the overall scenario. Second read: identify inputs, outputs, and the core logic.

Step 2: Identify the Sub-Problems (3 minutes)

Paper 1B questions are always split into parts (a), (b), (c), (d). Each part is a smaller, solvable problem. Attack them one at a time.

Step 3: Write Pseudocode Before Python (5 minutes)

On the exam paper margin, jot down what each part needs to do in plain English:

(a) Read data from file
(b) Create Student class
(c) Find student with highest score
(d) Output formatted report

Step 4: Code Part by Part (25 minutes)

Start with the easiest part. If part (a) looks hard, do part (b) first — they often don't depend on each other.

Step 5: Test Each Part Before Moving On (5 minutes)

Trace through with the sample input. Verify your output matches the example output shown in the question.

Common Paper 1B Patterns

Pattern A: File → Process → Output

with open('data.txt') as f:
    records = [line.strip().split(',') for line in f]

# Process each record
results = []
for r in records:
    # transformation logic
    results.append(...)

# Output
for r in results:
    print(f"{r[0]}: {r[1]}")

Pattern B: Class with Methods

class Entity:
    def __init__(self, ...):
        ...
    def method1(self):
        ...
    def method2(self):
        ...

# Create instances and use them
entities = [Entity(...) for _ in range(n)]

What to Do If You're Stuck

1. Attempt a simpler version. If asked to handle 100 records, write code that handles 1 first.
2. Skip that part and move on. Follow-through marking means later parts still score.
3. Write pseudocode if you can't write Python. Partial marks for logic.
