Interligence
Interligence is an AI-powered SAT Math practice platform designed to replace fragmented, outdated study methods with a cohesive, adaptive, and intuitive solution. The project aimed to reimagine SAT prep from a design perspective—where user motivation, clarity of feedback, and adaptive learning are built into every screen. By focusing on Thai high school students preparing for international programs, we created a tool that feels approachable and effective, even under exam pressure.

PROBLEM
Students weren’t just struggling with math, they were struggling to even find the right tools to practice it properly.
Our research revealed that current SAT Math practice methods, such as textbooks, past papers, and online platforms, often fall short. Students faced fragmented resources, outdated formats, and lacked clarity on their weak spots. Instructors also noted the absence of accessible, structured, and learning tools aligned with the new digital SAT.
Solution
An AI-powered platform for personalized SAT Math practice
To tackle these issues, we introduced "Interligence," an AI-powered SAT practice platform that offers AI-generated practice tests for a personalized learning experience and performance tracking to help students improve efficiently, with an intuitive user interface that simulates real exam conditions. The platform targets high school students in Thailand who aim for international programs.
Research
Scattered prep tools and resources left students overwhelmed and insecure
We began with in-depth qualitative interviews involving 15 participants: 4 high school students, 7 university freshmen, and 4 SAT instructors. The aim was to explore their study behaviors, tool usage, frustrations, and expectations.
What We Discovered:
Students juggled multiple sources without clear guidance
Many had taken practice tests but didn’t know what to do afterward
Instructors found it difficult to recommend any all-in-one solution
To deepen our understanding, we conducted a competitor analysis of four commonly used SAT prep tools
To visualize how these tools compare to one another (and to our future solution), we plotted them on a Price vs. Ease of Use matrix.
Requirement Gatherings
Filling in the Blanks: Prioritizing what students actually need
To ensure the product addressed the pain points, we started by translating user research into actionable product requirements where we uncovered recurring frustrations around SAT Math preparation, which we identified as follows:
Intuitive & Familiar User Interface
Users needed Bluebook-style interface that helped them be familiar the real exam environment.Skills Breakdown
Students needed to quickly identify their area of weakness and tackle those immediately.Track & Review Previous Mistakes
There was no structured way for users to revisit and learn from past mistakes
Persona
To anchor our decisions around the target audience, we created a primary persona based on the most prominent user group: high school students preparing for the SAT. This persona guided our design priorities and helped us stay focused on user behavior, motivations, and challenges.
After identifying user needs, we translated them into potential features. To help us prioritize, we organized all ideas into an Impact–Effort Matrix. This allowed us to filter out low-impact or high-effort features and focus on those that delivered the most value within our timeline.
Prioritized MVP Features
AI-Powered Practice Test: For unlimited, adaptive test simulations (Major Requirement)
Analytics Dashboard: For visualizing progress and performance trends
Book of Improvement: For reviewing and retrying missed questions
Secondary features like streak tracking and topic-specific practice were scoped for future iterations based on their long-term value.
Executions
Turning "Practice" into "Progress", and "Mistakes" into "Improvement"
We set out to design an experience that didn’t just feel smart but also make it felt supportive. Our challenge was to mirror the structure and pressure of the SAT while reducing cognitive friction and keeping students focused.
Wireframes
We used wireflows and page-level wireframes to define clear, intuitive interactions across the Practice, Analytics, and Improve sections. Our wireflows helped us map out the complete user journey; highlighting key decision points like starting a new test, reviewing results, and tracking progress over time. These flows ensured that users could move through the app with minimal friction and maximum clarity.
We also designed detailed wireframes that explored content hierarchy, functional layout, and visual grouping. Each page was structured to support focused actions and quick comprehension, following principles like Fitts’ Law for tap targets and Hick’s Law to reduce decision fatigue.
Visual Design (UI)
In the high-fidelity UI stage, we applied a token-based design system to maintain visual consistency and ease scalability. We used Figma variables for color schemes, spacing, and typography to streamline iteration and responsiveness.
Iterations from Usability Tests
To validate our design decisions, we conducted usability testing with 10 participants across our target user group. Using the think-aloud method, we observed how users navigated through key flows—taking a practice test, reviewing results, and analyzing performance.
The testing surfaced subtle but critical friction points that shaped our final design:
“Book of Improvement” Terminology Caused Confusion
Several users didn’t immediately understand what the term referred to. To resolve this, we renamed it to a more action-oriented label and added a brief description beneath the section title to clarify its purpose.
Analytics Dashboard Overwhelmed First-Time Users
While users valued the data, they found the layout too dense and hard to scan. We restructured the page into digestible sections, and used stronger visual hierarchy to guide focus.
Practice Flow Felt Abrupt and Unprepared
Several users reported feeling caught off guard when the practice session began immediately after clicking “Start Practice.” There was no transition or opportunity to mentally prepare. In response, we introduced a confirmation pop-up screen that appears after clicking the button. This gave users a moment to get ready and reduced anxiety before entering the test environment.
These small but impactful changes were driven by user feedback and directly improved usability, reducing hesitation and boosting confidence across critical user flows.
Results
A Digital SAT experience that motivates practice and builds confidence
By combining intelligent features with human-centered design, Interligence delivered more than a test prep tool—it created a guided, stress-reducing learning environment that students returned to. The platform didn’t just simulate exams; it gave students structure, clarity, and a sense of progress they could trust.
Usability Testing Outcomes
The platform achieved strong usability metrics that validated the success and effectiveness of our design decisions.
IMPACT
Bridging the gap between "Practice" and "Progress"
Interligence tackled a very real and growing problem in standardized test preparation where students aren’t lacking motivation but they’re lacking structured, supportive tools that help them improve. By focusing on the user experience, we designed a platform that simplifies complex data, mirrors the SAT interface, and motivates learners through clarity and feedback.
This project is not just a senior project, it has the potential to evolve into a real-world solution for students in Thailand and beyond—scalable across subjects, adaptive to learning styles, and affordable enough to level the playing field. With the rise of AI in education, Interligence demonstrates how thoughtful design can humanize technology to meet actual student needs.
Next Steps
Building on this foundation, we envision Interligence growing into a fully scalable learning ecosystem:
Support more exams such as ACT, TOEFL, or Thai university entrance tests
Add topic-based learning flows with progress tracking and AI-driven study plans
Integrate detailed AI explanations for question solving, not just correct answers
Build a collaborative version where instructors can assign practices and track student analytics
Develop mobile support and offline modes to increase accessibility
By continuing to learn from real users and validating every step through research and testing, Interligence can expand from a prototype into a product that truly transforms the way students prepare—confidently and consistently.
