TM 11120J - The Open University Question 1 (a) When the spacebar is pressed, the user is asked to input the students name, which, in this case, is Faria. Faria is then stored as a "name" variable. The user is then asked to input their test score of 72, this is then stored as a "math_test_score" variable. The "percentage_score" is then worked out by using the variable "math_test_score" * 1.25, which then provides us with a percentage out of 100. The sprite then informs us of the "percentage_score" for Faria. In this case, Faria's "percentage_score" is higher than 75% so therefore her name which was stored in the "name" variable, is now added to the "math_challenge_list" list. The program was able to decide if Faria was legible for the "math_challenge_list" by using the "IF percentage_score > 75 THEN" function. An excellent fully detailed description. (b) i. 80 Make it clear what this number represents. Although this might be suitable in an extended version it is not being used in this program. The percentage multiplier, 1.25, might be stored in a constant. ii. MAXIMUM_SCORE Good to see the naming convention for constants has been followed. (c) Page | 1 .

Excellent (d) i. Page | 2 Natalie George TM111 TMA02 L5490096 Figure 2– A screenshot of an OUBuild script which further categorises students based on their math test scores than the script in Figure 1 An excellent solution. It is good to see the use of nested IF statements, these are efficient and you will meet them frequently in the future. ii. An alternate script structure that could have been used would have been 3 separate IF__THEN blocks, one for if the score was >75% to put then in the math challenge list, another for >50% but <75% for the good math score list and finally a <50% list for the low test scores. A very well explained answer.

An excellent solution meeting all requirements. Great work.

The algorithm is more detailed than needed, it should just show the overall strategy being used. The following would be a full answer: Input word Repeat (length of word) times Append current letter to new word If current letter is in the first half of the alphabet then Append current letter to new word Display new wo
