Generate interactives from Wikipedia, YouTube, PDFs, etc.
Create a list of all the subjects you want to learn. Define the abilities you want and your target skill level. Then gather a list of resources.
Use your resources to generate interactive learning materials. You can automatically generate flashcards (basic, cloze deletion, visual occlusion), multiple choice questions, fill in the blanks, etc.
Interactives go way beyond flash cards. There's a 'Lesson Mode' where you can intersperse content with interactives to ensure you understand what you're learning.
After you've generated your interactive learning material, you can set up your daily study sessions. There's a built-in spaced repetition system. And you can track your progress with a review system to ensure you're moving towards your desired skills.
