A smart, AI-powered platform for generating and evaluating practice problems.
📽️ Demo Video
Let'sPrep is a React Remix-based educational platform that helps users practice problem-solving in various subjects by leveraging OpenAI for automatic problem generation and evaluation.
Users can enter a topic or a specific problem, and the system generates short answer, multiple choice, true/false, and long answer questions, while also providing AI-driven grading and step-by-step explanations.
- React Remix – Server-side rendering & optimized routing
- Tailwind CSS – Responsive UI styling
- KaTeX – LaTeX rendering for mathematical expressions
- Golang – High-performance REST API
- Fiber – Fast Golang web framework
- MongoDB – NoSQL database for storing user data and generated problems
- OpenAI API – For generating problems, grading responses, and providing explanations
- RESTful API – Clean architecture for interacting with the frontend
Users enter a topic or an example problem (e.g., "Solve for x in 2x + 3 = 7").
The backend uses OpenAI to generate various problem types:
- Short Answer: Users input a text response, and AI grades it.
- Multiple Choice: AI provides options and evaluates the selection.
- True/False: Users select an answer, and AI verifies correctness.
- Long Answer: AI grades the user’s response and provides detailed feedback.
The system sends user-submitted answers to OpenAI for grading and explanation generation. AI provides:
- Numerical grade (0-100)
- Step-by-step solution breakdown
- Feedback on mistakes
- Users will be able to create accounts and track progress over time.
- MongoDB will store user history and allow revisiting past problems.
