The Lighthouse is your free space to study, practice, and track progress — all in one place.
Go to the Explore page to find learning materials by subject or category. We offer both Study Mode and Practice Mode depending on your goal.
Study Mode is designed for reviewing important concepts. You'll see explanations, summaries, or examples — perfect for learning new material or refreshing your memory.
Once you're ready, switch to Practice Mode to test yourself with quizzes and interactive questions. You can retry as many times as you'd like — no pressure, no penalties.
Log in with your Google account to keep track of your study and quiz activity. All progress is saved to your Dashboard, where you can monitor improvement over time.
Don't want to log in? No problem. All materials are freely available without creating an account. Your privacy matters to us.
Feeling competitive? Practice quizzes also count toward a friendly leaderboard — visible only if you're logged in. It's optional, fun, and entirely up to you.
If you ever need help, visit our Help Center, Contact page, or message us on Twitter.
Whether you want to study at your own pace or sharpen your skills through practice — The Lighthouse is built to guide your journey.
