A tutorial explainning the use of if, else, and Boolean logic in computer programming.

Learn how omcputer programs also make decisions, using Boolean expressions (true/false) inside conditionals (if/else).

Practice using iteration in computer programs to repeat code until a boolean expression is true for programs written in the AP CSP pseudocode, in this set of practice questions designed for AP Computer Science Principles students.

Practice defining procedures with parameters for programs in the AP CSP pseudocode, in this set of free practice questions designed for AP Computer Science Principles students.

Practice using procedures with parameters for computer programming.

Practice programming problems using procedures with return values.

Learn how programmers repeat code using a programming construct like the while loop.

Learn how to pair Khan Academy's course mastery system with assignments in order to best meet the needs of all students.

Khan Academy has teamed up with College Board, the makers of the SAT, to create free, official SAT practice for all students. Get personalized practice recommendations based on your performance on the PSAT/NMSQT, check out helpful video...

Procedures can compute values for the rest of the program to use by sending back return values.
