Every tier, every price — so you can find the right fit for your budget.
All three offer guarantees — but the fine print varies significantly.
If your score doesn't improve by 200 points, you can retake the entire course for free. TestMasters reports that fewer than 1% of students ever request a retake — a strong indicator of confidence in results.
💡 Key differentiator: Free retake (not just money back), with an extremely low claim rate.
Score higher than your baseline or get your money back or extended access to continue studying. Straightforward, but the bar is simply "any improvement" — not a specific point increase.
💡 Key differentiator: Money-back option gives financial flexibility, but lower bar for the guarantee.
On the premium 1400+ Course tier: score 1400+ or improve by 150 points, or get your money back. Lower tiers offer a "Better Score" guarantee only.
💡 Key differentiator: Highest target-score guarantee, but only on the premium $1,849 tier.
