AI Integration for Personalized Exam Prep App

# Freelancer Project Description — AI-Powered Personalized Exam Preparation

I have an **education application already available on the Google Play Store** for students preparing for government/competitive exams. I want to integrate an **AI/LLM-powered personalized learning and exam analysis system** into the existing application.

### What I Want to Build

The AI should use the student's **existing activity and performance history**, including:

* Exams/mock tests attempted
* Questions attempted and skipped
* Correct and incorrect answers
* Subject-wise performance
* Chapter-wise performance
* Topic-wise performance
* Previous test scores and accuracy
* Question difficulty/performance patterns
* Time spent, where available

Based on this data, the AI should build a **personalized understanding of each student's preparation level**.

### AI Features Required

The AI should be able to identify and explain:

* **Weak subjects**
* **Weak chapters**
* **Weak topics**
* Strong subjects, chapters, and topics
* Frequently repeated mistakes
* Areas where the student is improving
* Areas requiring immediate attention
* Overall preparation level and performance trends

For example, the AI could tell a student:

> "Your Mathematics performance is strong overall, but Algebra and Trigonometry are currently your weakest areas. You are performing well in Physics and General Knowledge. You should focus on Algebra first because your accuracy has remained below your target across your last 5 tests."

### AI Chat Assistant

I also want to provide an **AI chat interface inside the application** where students can ask questions about their preparation.

For example:

* "What should I study today?"
* "What are my weakest topics?"
* "Why am I scoring low in Maths?"
* "Which chapters should I revise before my next mock test?"
* "Am I ready for the exam?"
* "Create a 7-day study plan for me."
* "What should I focus on based on my last 10 tests?"

The AI should answer using the student's **actual performance/history**, rather than giving generic advice.

### Personalized Preparation Recommendations

The AI should continuously recommend actionable steps to improve preparation, such as:

1. Which subject to study next
2. Which chapter/topic to prioritize
3. Which topics need revision
4. Which mock tests to attempt
5. When to practice PYQs
6. How much time to allocate to different subjects
7. When to revisit previously weak topics
8. Personalized short-term and long-term study plans

The ultimate goal is to create an **AI personal exam preparation coach** that understands each student's preparation history and guides them toward better performance in government exams.

### Technical Expectations

The freelancer should have experience with:

* LLM/API integration
* OpenAI or other LLM providers
* AI chat systems
* Personalized recommendation systems
* RAG/context management where appropriate
* Backend API integration
* Database/query optimization
* Student performance analytics
* Secure handling of student data
* Mobile app integration

The existing application and backend are already developed, so the freelancer will primarily need to **integrate the AI layer with the existing application, database, APIs, and student performance data**.

I am looking for someone who can suggest the **best architecture, LLM approach, data pipeline, prompting strategy, and implementation plan**, rather than simply connecting a chatbot API.
