What's free, exactly?
The first two coding modules (9 full lessons with the live code editor), the entire 130-question CDL practice test, all subject practice — math, science, chess, web dev, AI tools, trading — every quiz, and every game. Free means free: no card, no trial clock.
What does All Access unlock?
Coding modules 3–12: data structures, OOP, trees & graphs, algorithms, databases, web development, software engineering, advanced algorithms, systems, system design, and the capstone — 41 more lessons, plus every premium module we ship in the future.
Can I cancel anytime?
Yes. Subscriptions are month-to-month. Manage or cancel in one click from your dashboard via the Stripe billing portal — you keep access until the end of your billing period.
Is lifetime really lifetime?
Yes. Pay $89 once and you have All Access permanently, including all future premium content. No recurring charges.
Do I need to pay to run code?
No. Python and JavaScript run in your browser on every free lesson. C++ and Java run through a free server-side service with a fair-use rate limit.
I just want the CDL exam simulator — do I need All Access?
No. CDL Pro is $19 once and unlocks CDL Exam Mode forever (it's also included in All Access). Category practice on the CDL page stays free either way.
