I Built an AI Mock Test Platform Using Free APIs — Here’s What Works and What Breaks

I’m a student, and I noticed something:

Most people don’t fail exams because they don’t study.
They fail because they don’t practice enough.
So instead of making another “notes app”, I built an AI-powered mock test platform

What It Does

• Generates mock tests instantly
• Evaluates answers
• Identifies weak areas

Tech Stack

• Frontend: Next.js (Vercel)
• Backend: Supabase
• Database/Auth: Supabase
• AI: Groq API (free-tier models)

This is still an MVP so feel free to suggest any improvements.
