Once have covered Context API, I would highly suggest navigating to the next section and complete the projects 12-13 (sidebar-modal,stripe submenus). After that you can work on project 14, assuming you completed the useReducer portion in tutorial.

If you did not work on the project number 1, please make sure you follow the starter project install, so please start with Intro lecture. While it's not mandatory, working on projects is the best way how you can get better at React.
