Quick Questions

Shade in the A or B circle for each question.

1. Which line is written in the correct pseudocode style?

A IF score > 10 THEN

B if score > 10 then

2. How should the steps inside an IF block be laid out?

A Lined up with the IF at the left edge

B Indented under the IF line

3. Where should ELSE be placed?

A Lined up directly under its matching IF

B Indented further than the steps above it

4. Which layout follows the one step per line rule?

A SET total TO 0 SET count TO 1

B SET total TO 0 SET count TO 1

5. Which REPEAT block is laid out correctly?

A REPEAT 3 TIMES OUTPUT "Hi"

B REPEAT 3 TIMES OUTPUT "Hi"

Match the Pairs

Draw a line connecting each item on the left to its match on the right.

Left column		Right column
1IF score > 10 THEN OUTPUT "Pass" ELSE OUTPUT "Try again"		AELSE is indented in line with the steps instead of lining up with its IF. It should start in the same column as IF.
2REPEAT 3 TIMES OUTPUT "Hello"		BThe keywords if, then and output are in lowercase. They should be written in capitals: IF, THEN and OUTPUT.
3Write one step per line, with keywords in capitals		CThe indented step is repeated; the keywords are in capitals
4Indent a nested block further than the block around it		DELSE lines up with its IF, and the steps inside each part are indented
5if age >= 13 then output "Teen"		ESET total TO 0 INPUT age OUTPUT age
6IF score > 10 THEN OUTPUT "Pass" ELSE OUTPUT "Try again"		FREPEAT 5 TIMES IF key = "Q" THEN OUTPUT "Quit"

Answer Key

Pseudocode layout: capital keywords and indentation

Section A: Quick Questions

A — IF score > 10 THEN

B — Indented under the IF line

A — Lined up directly under its matching IF

A — SET total TO 0 SET count TO 1

B — REPEAT 3 TIMES OUTPUT "Hi"

Section B: Match the Pairs

IF score > 10 THEN OUTPUT "Pass" ELSE OUTPUT "Try again" → ELSE lines up with its IF, and the steps inside each part are indented

REPEAT 3 TIMES OUTPUT "Hello" → The indented step is repeated; the keywords are in capitals

Write one step per line, with keywords in capitals → SET total TO 0 INPUT age OUTPUT age

Indent a nested block further than the block around it → REPEAT 5 TIMES IF key = "Q" THEN OUTPUT "Quit"

if age >= 13 then output "Teen" → The keywords if, then and output are in lowercase. They should be written in capitals: IF, THEN and OUTPUT.

IF score > 10 THEN OUTPUT "Pass" ELSE OUTPUT "Try again" → ELSE is indented in line with the steps instead of lining up with its IF. It should start in the same column as IF.

Section C: Definitions

pseudocode layout — Write keywords like IF, THEN, ELSE and REPEAT in capitals, one step per line, and indent the steps inside each structure so ELSE lines up with its IF.

Section D: Fill in the Blanks

IF score >= 50 THEN
    OUTPUT "Pass"
ELSE

REPEAT 3 TIMES
    OUTPUT "Hi"
END REPEAT

IF age >= 13 THEN
    OUTPUT "Teen"
END IF

IF raining THEN
    OUTPUT "Take umbrella"
END IF

REPEAT
    count ← count + 1
UNTIL count = 5

Section E: Spot the Error

B — Pseudocode keywords must be written in capitals. IF and THEN should be written as: IF age >= 13 THEN.

B — Keywords must be all capitals, not just start with a capital letter. It should be: IF mark >= 50 THEN.

B — TIMES is a keyword, so it must be in capitals like REPEAT. The line should be: REPEAT 5 TIMES.

C — DISPLAY is a keyword, so it must be in capitals even when it is indented inside the loop. It should be: ' DISPLAY lives'.

C — Pseudocode has one step per line. The two DISPLAY steps must be split onto separate lines.
