Common Questions

How long is launch pricing available?

Launch pricing is available for a limited time. When you subscribe now, you lock in this rate — even if prices increase later, your rate stays the same as long as you remain subscribed.

How much do I save with annual billing?

Annual billing saves you 33% — that's $40 per year. You're billed once annually ($80 instead of $120) and get uninterrupted access to all Pro features.

Is the free account really free?

Yes, completely free. No credit card required. You get 2 daily practices per section with AI-powered scoring aligned to ETS rubrics, full progress tracking, and 6 minutes of Petra speaking coach to try. It's the perfect way to experience PrepEx and build a consistent practice habit.

What makes Petra special?

Petra is your AI speaking coach that holds real-time conversations with you, just like a human tutor. She provides instant feedback on your pronunciation, fluency, and content while adapting to your skill level. Pro members get 40 minutes per month (2400 credits) that refresh automatically — enough for consistent weekly practice sessions.

Why upgrade to Pro?

Pro unlocks unlimited AI-generated questions and grading across all four sections, plus 40 minutes of Petra per month. You get full-length practice tests with complete AI analysis, intelligent analytics that reveal exactly where to focus your study time, and AI-generated questions that ensure fresh practice content every session.

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.
