🎯 Objectives

• Analyze how students progress from Year 1 to Year 3 based on subject choices.
• Visualize the flow using a Sankey diagram for intuitive understanding.
• Examine the distribution of elective choices in Year 3 using a violin plot.
• Derive insights that can help in curriculum and elective planning.

📘 Introduction

• Students often choose from a pool of elective courses during their academic journey.
• Identifying patterns in these choices can reveal subject popularity, transition trends, and potential load imbalance.
• This project uses real-like synthetic data to track and visualize those movements.

📊 Dataset Used

File Name: synthetic_grade_sheet.csv

Columns: - Subject_1 to Subject_10: Core subjects from Year 1 to Year 3. - Elective: The elective subject chosen in Year 3. - Roll Number: Unique identifier for each student.

Why this dataset? - It provides a structured academic record. - Includes consistent subject sequences. - Offers elective choices for final-year students—ideal for pathway analysis.

🔍 Methodology Summary

• Selected 1 subject from each year:
  • Year 1: Subject_1
    
  • Year 2: Subject_5
    
  • Year 3: Elective
• Created a Sankey diagram to show transitions from Year 1 → 2 → 3.
• Built a violin plot to analyze Year 3 elective choice density.

🧠 Insights & Conclusion

• Majority of students transition to a limited set of electives.
• Some electives are highly favored, indicating strong interest or better teaching quality.
• The Sankey diagram effectively highlights transition bottlenecks or concentrations.
• This approach can assist faculty and departments in:
  • Adjusting elective offerings.
  • Balancing student-to-teacher ratios.
  • Forecasting demand for upcoming academic years.
