AI Exam Practice & Open-Ended Grading for Singapore Students
🎯The Problem It Solves
In Singapore, parents and students frequently exhaust finite school past-year exam papers. While multiple-choice questions are easy to check, open-ended science and humanities questions require exhausting manual marking. Tutors are expensive, and generic AI chatbots often generate content that strays outside the Ministry of Education (MOE) syllabus.
Professor Turtle was built to solve this: infinite practice questions strictly tuned to the Singapore syllabus, accompanied by rubric-aware automated grading.
⚡Key Capabilities & Architecture
Curriculum selection spanning Primary 1 to Secondary 4 across English, Math, Additional Math, Primary & Lower Sec Science, Physics, Chemistry, Biology, Geography, History, and Literature set texts.
Grades student answers against exact scoring rubrics, pinpointing missing keywords and giving constructive step-by-step guidance rather than just a score.
Students write on physical paper, snap a photo, and the vision pipeline transcribes their handwriting and evaluates their solution directly.
Resilient backend routing between primary and alternative server endpoints (OpenCode DeepSeek V4 Flash, Google Gemma, OpenRouter models) to ensure 24/7 uptime for students.
