This study guide covers control flow in programming, focusing on selection with if statements, else statements, and Boolean expressions. It explains the structure and logic of these statements in pseudocode and Python, provides practice questions (MCQs and FRQs) involving conditional logic, and offers final exam tips emphasizing the importance of these concepts, indentation, and combining them with other programming elements like loops and data structures.

Hey there! Let's get you totally prepped for the AP CSP exam. We're going to make sure everything clicks, so you can walk in feeling confident. Let's dive in!

#🚀 Control Flow: Sequencing, Selection, and Iteration

#Selection: Making Decisions with `if` Statements

We're diving into selection, which is all about making choices in your code using conditional statements (aka if statements). Think of it like a choose-your-own-adventure book, but for computers! 🕹️

#What are `if` Statements?

if statements allow your program to execute different code blocks based on whether a condition is true or false.
They use Boolean expressions (expressions that evaluate to true or false) to decide which path to take.

Key Concept

if statements are fundamental for creating dynamic and responsive programs. They're how your code makes decisions!

#Basic `if` Statement Structure

Here's how a basic if statement looks in pseudocode:
