An established UK exam-prep business trusted by 100,000+ families, now building an adaptive, AI-powered platform (Exam Beacon) on top of its expert-written content.

The situation
Turning decades of exam preparation expertise into an AI-powered adaptive learning platform that personalizes exam preparation for every child.
Exam Papers Plus had spent years helping over 100,000 families prepare for grammar and independent school entrance exams with high-quality, human-written practice papers. But it sold static PDFs with no feedback loop: families completed materials and Exam Papers Plus never saw the results, with no way to personalize prep or track readiness. In a fragmented exam landscape where every school tests differently, quality preparation felt accessible only to families who could afford private tutoring, and Exam Papers Plus didn’t have the technical team to build the digital product that would change that.
Before
- Deep exam expertise, but delivered as static PDF practice papers
- No feedback loop: no view of results, progress, or weak areas
- Quality, personalized prep felt limited to families who could afford tutors
After
- An adaptive platform that personalizes prep to each child’s target school
- Every session generates data that sharpens the next one
- Expert, human-written content plus AI support, accessible to every family

The approach
Exam Papers Plus is an established UK education business that has spent years helping families prepare children for grammar and independent school entrance exams.
Exam Papers Plus is an established UK education business that has helped over 100,000 families prepare children for grammar and independent school entrance exams, built on high-quality, human-written papers from subject-matter experts. Its model was proven but offline: parents bought downloadable PDFs and practiced at home, with no feedback loop back to the company.
CEO Marc Wells saw the opportunity to build something different, an adaptive digital platform that pairs the company’s deep exam expertise with modern technology to personalize preparation for every student. What Exam Papers Plus didn’t have was the technical capability to build it, so it partnered with OAK’S LAB to take the idea from concept to a running product.

The work
Build an adaptive learning platform from scratch that personalizes exam prep for every child.
The mandate was a true greenfield build: create Exam Beacon, an end-to-end platform that generates a personalized preparation path for each student based on their target school and exam board, adapts to performance data, and adds AI tutoring and grading, without losing the human-written, expert-reviewed content that is Exam Papers Plus’s edge.
And it had to prove itself fast, going from concept to a live pilot with real families to validate the adaptive algorithm before a wider rollout.

The solution
OAK'S LAB deployed a full autonomous team and built Exam Beacon end to end.
We deployed a full autonomous team of eight, Product, Design, and Tech Leads, four full-stack engineers, and QA, owning the entire lifecycle from discovery and architecture through a dual-track delivery phase to a live pilot with real users. The team worked directly with Marc to shape the vision and translate it into a working product.

Adaptive Learning Algorithm
Starts with a 50+ question diagnostic across four subjects and 70+ question types, then weights every session toward the student’s weak areas and updates their profile after each one, so preparation gets more targeted with every interaction.

AI Study Buddy & Grading
A Socratic in-session helper that guides students to the answer with progressive hints, with safeguarding built in for young learners, plus AI grading of open-response work that returns structured, tutor-quality feedback in seconds, calibrated against real tutor evaluations.

Parent & Learner Dashboards
Progress monitoring, milestone alerts, and readiness tracking for parents, and an engaging, lightly gamified experience (badges, streaks) that keeps young learners motivated through months of prep.

Practice Sessions & Mocks
Partial and full mocks that replicate the target school’s exam, online or PDF, scheduled across the preparation calendar and scored against the adaptive profile for a realistic read on exam-day readiness.
The results
A publishing business, reborn as an adaptive platform.
Concept to live in months. Exam Beacon went from a blank slate to a live product, with 35 families using it daily before the public launch.
Adaptive algorithm validated. Real pilot usage confirmed the algorithm correctly identifies weak areas, adjusts practice, and improves readiness over time.
AI that levels the playing field. Human-written, expert-reviewed content plus AI tutoring and grading gives every family the personalized support once available only through expensive private tutors.
Built to scale. The architecture supports multiple exam boards, additional exam types, and a growing user base, with expansion already on the roadmap.
