How does pricing compare?

CasperPractice: Freemium. Freemium. A free tier gives access to practice questions with limited AI coaching (the first attempts are coached at no cost), while the Pro plan is a paid subscription that unlocks unlimited scored attempts and the 4th quartile money-back guarantee. Pricing is discounted periodically on the site. 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are shown on the course pages after you select a track, so treat any figure you see in older reviews as potentially out of date.
