An AI-powered exam preparation platform that actually prepares students, not just tests them. Marvel PTE and Langcert Academic are SIAGB’s own EdTech products, serving 85,000+ test takers across 900+ institutes with real-time AI scoring, adaptive learning, and analytics that show exactly where to focus.
The Challenge
English proficiency exams like the PTE Academic are high-stakes. A few points can determine whether someone gets their visa, university admission, or professional registration. The pressure is real. And yet most preparation tools are, frankly, not up to the job.
Static question banks with no feedback. Delayed scoring that tells you what you got wrong but not why. No real insight into where to actually focus your study time. Students practise endlessly without knowing if they’re getting better or just repeating the same mistakes.
Here’s a number that tells the story: according to Pearson’s own data, approximately 35% of PTE test takers don’t achieve their required score on the first attempt. That’s not because they’re not capable. In most cases, it’s because their preparation didn’t target the right areas.
Coaching centres and language schools face their own version of this problem. They need technology that keeps pace with how exams evolve, provides measurable outcomes for students, and scales without proportionally increasing instructor workload. Off-the-shelf solutions are either too generic to be useful or too expensive to customise for their specific needs.
The gap between what students need and what existing tools deliver is exactly the gap we set out to close. Not as consultants advising from the sidelines. As builders who delivered the product themselves.
Our Approach
We didn’t just consult on EdTech. We built it. Marvel PTE and Langcert Academic are our own AI-powered exam preparation platforms, developed in-house and serving real users with real results. These aren’t proof-of-concept demos. They’re live SaaS products with 85,000+ test takers and 900+ partner institutes.
Our AI scoring engine analyses spoken and written responses in real time. Students get immediate, detailed feedback that closely mirrors official exam marking criteria. Not just a score, but specific guidance on what to improve and how. The custom AI models powering our scoring were trained on thousands of exam responses to achieve accuracy that students consistently report aligns within a few points of their actual exam results.
The adaptive learning system tracks each student’s strengths and weaknesses across every skill area. It automatically adjusts their study plan to focus on the areas that will move their score the most. If a student is strong in reading comprehension but struggling with spoken fluency, the system shifts focus accordingly. Every practice session is personalised.
For institutions, we provide analytics dashboards showing cohort performance, predicted pass rates, and areas where teaching intervention will have the highest impact. This transforms coaching from intuition-based to data-driven.
Building these platforms gave us deep, practical expertise in AI education technology. From the machine learning models that power scoring, to the user experience design that keeps students engaged, to the infrastructure that handles thousands of concurrent practice sessions. When we work with EdTech clients on app development or SaaS development, we bring the perspective of a team that has delivered, scaled, and maintained real products in this space.
Platform Capabilities
So what actually separates an AI-powered preparation platform from a basic practice test website? Quite a lot, actually:
| Feature | Basic Practice Sites | Our AI Platform |
|---|---|---|
| Scoring | Delayed or manual | Real-time AI scoring |
| Feedback | Score only | Detailed improvement guidance |
| Learning path | Same for everyone | Adaptive to each student |
| Question freshness | Static bank | AI-generated, continuously updated |
| Institution analytics | None | Cohort tracking, predicted pass rates |
| Scalability | Limited | Thousands of concurrent sessions |
According to HolonIQ, global EdTech spending is projected to reach USD $10 billion by 2027 in the Asia-Pacific region alone. AI-powered adaptive learning is the fastest growing segment, and the reason is simple: it works. Students learn faster when the system adapts to them rather than forcing everyone through the same linear path.
Now, we’ll be the first to admit that AI scoring isn’t perfect. No scoring system is, including human markers (who also have inconsistency issues). But the combination of speed, consistency, and detailed feedback makes AI-assisted preparation significantly more effective than traditional methods. Students can practise a speaking task and get scored feedback in seconds rather than waiting days for a teacher to review a recording.
