Progress Tracker: a PDF poster that you can print and cross out as you complete the exercises to help you track your progress.
Cornell Note-taking Method Page Format: a PDF format that you can print to take notes following the Cornell Note-taking Method (a page divided into three sections to write your notes, comments, and summary).
Code Notebook Format: a PDF format that you can print to write your solutions or the sample solutions by hand, analyze the code, and add your comments.

The Coding Challenges Cover:

Strings
Lists and Tuples
Dictionaries
Conditionals
Loops
Recursion
