Please note that our app is different from our site and not every section in the courses or Paths has a practice pack for you to work on the app and these sections will appear greyed out. Any grayed-out sections are placeholders for the content that does not have review content at this time. Apologies for the confusion.
To help provide you with some clarity on how to best use the app, we recommend that the vast majority of your learning be completed online. When you are away from your computer, you can use the app to practice the topics you are learning. With the Codecademy Go mobile app, you can practice and review coding concepts that will get you closer to achieving your learning goals.
