How does pricing compare?

Brilliant: Freemium. Brilliant uses a freemium model: a limited free experience is available, while a Premium subscription unlocks the full course library and unlimited practice. Annual plans are the cheapest per month, and there are separate school/classroom plans. Prep Edu: Paid. Paid, course-based. Prep Edu sells structured IELTS, TOEIC, HSK and PrepTalk English packages rather than a single flat subscription, and the exact fee depends on which program and length you choose. Current prices are shown on the course pages after you select a track, so treat any figure you see in older reviews as potentially out of date.
