Activity 2: Investigate (Parsons Problem)

Drag and reorder the blocks to build the correct OCR pseudocode program.
The program should calculate whether the number is even using MOD.
Then check whether the number is high enough using >=.
Finally print one boolean result using AND.

Your Program

Activity 3: Modify

The starter program already checks if a mark is >= passMark.
Add code to print mark MOD 5.
Then output whether mark != 100.

Code Editor

Console

Run your code to check it.

Activity 4: Make

Use the complete OCR Reference Language IDE to solve the challenge.
Include at least one // comment.
Use arithmetic, comparison, and boolean operators.
Ask for two numbers and print several operator results.
Print a final TRUE/FALSE decision using AND or OR.
