Choose monthly billing at $39.99/month (20% off) or quarterly at $89.99 every 3 months (25% off, just $30/month). Both plans include all Pro features with no restrictions.

Is the free account really free?

Yes, completely free. No credit card required. You get 2 daily practice submissions (shared across all sections) with AI-powered scoring aligned to ETS rubrics, full progress tracking, and 360 Petra credits every month (3 minutes of speaking practice). It's the perfect way to experience PrepEx and build a consistent practice habit.

How does the TOEFL test discount work?

When you subscribe to PrepEx Pro, you'll receive a discount code via email after your first payment.

This discount applies to your official ETS TOEFL registration and can save you up to $30+ on test fees.

Why upgrade to Pro?

For less than a single tutoring session, you get a full month of unlimited practice. Pro removes all daily limits, gives you 6,000 Petra credits per month (50 minutes of AI coaching), unlimited AI-generated questions, AI-powered flash card creation, and intelligent analytics that reveal exactly where to focus your study time.

How accurate is the AI grading?

Our AI is trained on official ETS scoring rubrics and calibrated against thousands of scored TOEFL responses. It provides consistent, detailed feedback that closely mirrors human raters. While PrepEx gives you excellent practice and feedback, remember that only official ETS tests count for university applications.

Can I cancel anytime?

Yes. Cancel anytime from your account settings. You'll keep Pro access through the end of your current billing period, then automatically return to the free tier. No hassle, no questions asked.
