Example 1: Grade Calculator
GCSE Pseudocode:
score = input("Enter score: ")
if score >= 70 then
grade = "A"
elseif score >= 60 then
grade = "B"
elseif score >= 50 then
grade = "C"
elseif score >= 40 then
grade = "D"
else
grade = "U"
endif
print("Grade: " + grade)
Python Equivalent:
score = int(input("Enter score: "))
if score >= 70:
grade = "A"
elif score >= 60:
grade = "B"
elif score >= 50:
grade = "C"
elif score >= 40:
grade = "D"
else:
grade = "U"
print("Grade:", grade)
Example 2: Login Validation
username = input("Username: ")
password = input("Password: ")
if username == "admin" AND password == "secret123" then
print("Access granted")
loggedIn = true
else
print("Access denied")
loggedIn = false
endifThis study notes covers Practical Examples (GCSE Pseudocode & Python) within Selection (IF Statements) for GCSE Computer Science. Revise Selection (IF Statements) in 3.2 Programming for GCSE Computer Science with 15 exam-style questions and 8 flashcards. This topic shows up very often in GCSE exams, so students should be able to explain it clearly, not just recognise the term. It is section 7 of 10 in this topic. Use this study notes to connect the idea to the wider topic before moving on to questions and flashcards.
Practice questions for Selection (IF Statements)
Which programming construct is used to make a decision based on a condition?
Explain the difference between using ELSEIF and using nested IF statements to test multiple conditions.
