I did some research, and found out a pattern in Sparx Maths bookwork codes. (Changes letter to next in alphabet, and number by 10), so I made this project. You input the first bookwork code of the assignment and the project will generate the rest of the codes. Press space to add an answer, and the project will store the bookwork code and the answer in the workbook list. When you start a new assignment, section or finish a fast track quiz, press S to record your next bookwork code. This is because Sparx generates a code again on a new assignment. Press C to clear your workbook.
Inspiration by a different project I saw. (just search Sparx Maths, its the first thing)
