Mark Scheme
Question 1
(a)
One mark for each bullet point
Sequence
Selection
Iteration
(b)
Selection
A condition is used to decide whether code should be executed
Position = Position + 1 is only run if the IF condition is met
Iteration
code is executed repeatedly
The code in the repeat loop will be run several times (until Position = 100)
Question 2
(a)
One mark for each bullet point
A construct
Code is executed/run repeatedly/is looped
Until a condition is met/while a condition is true/a set number of times
(b)
While/do while
Repeat/repeat until/ do until/until
