# Dataset Overview

This dataset captures detailed interaction logs from 781 students in the Department of Computer Science at VNU-HCM University of Technology (Vietnam) over the 2023 and 2024 academic years. It covers two courses:

- **Programming Fundamentals (PF)** – first-year course; prerequisite: Introduction to Computing  
- **Data Structures & Algorithms (DSA)** – second-year course; prerequisite: PF  

Both courses run for six weeks, each week concluding with an exam on the previous week’s material.

## Student Section Grouping

Students are divided into three groups:

- **L (Regular):** 572 students across 15 classes, standard admission scores  
- **CC (Credit-Constrained):** 184 students across 3 classes, lower entrance scores with higher tuition  
- **DT (Deferred/Repeat):** 25 students retaking the course or improving prior grades  

## Weekly Topics & Assignments

1. **Week 1:**  
   - Object-oriented programming (OOP)  
   - Recursion  
   - ArrayList  
   - Singly linked lists  
2. **Weeks 2–5:**  
   - Doubly linked lists  
   - Stacks & queues  
   - Sorting algorithms  
   - Binary trees & AVL trees  
   - Search algorithms  
3. **Week 6:**  
   - Hash functions  
   - Graph theory  

Each week’s assignment has multiple programming questions (396 total), each with 1–10 unit tests (3,312 total).

## Logging & Actions

In our interactive coding environment, we record:

- `start_attempt`  
- `precheck` (public test cases; gives immediate feedback)  
- `save`  
- `check` (private test cases; more stringent, may incur penalties)  
- `finish_attempt`  

On private checks, students see only a numerical score.
