Question 1 (20 marks)
This question focuses on Part 1 (variables) Part 2 (constants, lists, arithmetic, joining strings) and Part 3
(selection).

Open the project .

This project is intended to implement a program to help the teacher record the number of books pupils
have read in a class reading scheme. The reading scheme comprises 20 books.

Before recording numbers of books read the teacher will start the program with the green flag. She will
then press her space key whenever she wants to record the number of books a pupil has read, which
she will enter as a whole number of books out of 20. If the percentage of books read is less than 70% it
is classed as low.

In this project we have provided a script and a
script. Consider the latter script carefully and then answer the questions
below.

a. Complete the following step-by-step description of what the script
does when the user starts the program with the green flag, then presses their space key, and
enters , and then . Your description should make clear what data is stored in the
variables and the list involved, and the result of any comparison that is made.
The user is asked to enter a pupil's name. Their input, , is stored in the variable .

The user is asked to enter the number of books the pupil has read ….

(4 marks)

b.

i. Identify a value in this program that might appropriately be stored in a constant. (There may
be more than one possibility but you are only required to identify one. You are not asked to
implement this constant.)
(1 mark)

ii. What might be an appropriate name for the constant you have chosen?
(1 mark)

c. Amend the and scripts so that:
if a pupil has read less than 70% of the books in the reading scheme their name is added to
the list

otherwise their name is added to a list (which you should
create and initialise appropriately).
