Pseudocode Index

Pseudocode tests logic, not syntax. Your main job is to trace variables accurately under time pressure.

Core pseudocode keywords

Keyword	Meaning
READ	take input
DISPLAY / PRINT	output
SET	assign value
IF / ELSE	conditional branch
FOR	fixed-count loop
WHILE	condition-based loop
REPEAT UNTIL	loop runs at least once
CASE	multi-way branching
RETURN	send value back from function

20-question strategy

Time: 20 minutes.

Target:

• 10 easy questions in first 7–8 minutes.
• 6 medium questions in next 8 minutes.
• 4 hard/long questions in remaining time.

Most common output traps

• Off-by-one loop boundaries: < vs <=
• Integer division
• Modulus %
• Variable update order
• Nested loops
• Array index starting from 0 or 1
• WHILE zero execution
• REPEAT UNTIL at least one execution
• Recursive base case
