Overview

TestMax is a digital education company best known for its comprehensive LSAT and Bar Exam prep courses. As part of TestMax’s expansion beyond legal exam prep, we created GREMax to explore opportunities in the broader graduate education market. Unlike our premium-priced LSAT and Bar courses, GREMax was positioned as a lower-cost subscription service aimed at high-volume adoption, with the long-term goal of converting users into higher-value tutoring customers.

As the product lead, I collaborated directly with the CEO, CTO, and engineering team to define and execute the vision for the platform. I led branding, UX, and visual design efforts to craft an experience that felt consistent with the TestMax suite while tailored to the needs and behaviors of GRE students.

Differentiation was key—unlike the relatively underserved legal prep space, the GRE market was highly saturated. In addition to strategic positioning, we faced technical and UX challenges unique to the GRE, including complex math notation, diagram-heavy questions, and a wider range of question types.

The final product balanced the technical demands of GRE content with a clean, approachable interface and intuitive study flow, allowing us to compete effectively in a crowded market.

Designing a Convenient GRE Study Companion

Challenge

The GRE market is far more saturated than the legal prep space TestMax was known for. Competing effectively required both strategic differentiation and solving real technical challenges unique to GRE content — complex math notation, diagram-heavy questions, and a wider range of question types than our existing platform had ever handled.

Approach

I led branding, UX, and visual design for the platform from scratch, building on the TestMax design system while tailoring the experience to GRE student behaviors. Key innovations included an inline practice question design that let students apply concepts immediately without switching contexts, and a hands-free vocabulary mode that enabled study while driving or multitasking — a meaningful differentiator for busy graduate applicants. The most significant technical challenge was implementing LaTeX notation to accurately render complex mathematical equations, which required close collaboration with engineering to solve.

Apple Watch App Design

Challenge

Vocabulary study is highly repetitive and benefits from short, frequent sessions — but no existing study tool was designed around the micro-moments of a student's day.

Approach

I designed a focused Apple Watch extension of GREMax centered on flashcard-based vocabulary review, adapting the interaction model to the constraints of a tiny screen. The simplified UI let users flip through cards and track performance in seconds, turning idle moments — waiting in line, between classes — into productive study time.

Impact

The Watch app reinforced GREMax's positioning as the most accessible GRE study tool available and was a meaningful differentiator in a crowded market.

Conclusion

GREMax was a beautifully designed product that helped students study efficiently and on their own terms. It saw solid user adoption and engagement in its first couple years, proving that there was demand for an affordable, accessible GRE study tool. However, despite its popularity, it ultimately did not drive the tutoring conversions TestMax had hoped for, leading to a strategic decision to sunset the app.

GREMax reinforced something important: product-market fit and design quality are separate problems. The app was well-designed and well-received — the strategic challenge was that GRE students weren't converting to the tutoring funnel the way LSAT students did. That insight was valuable, and it's the kind of outcome that only becomes clear when you ship and measure.
