turning 2 years of data into actual peace of mind
built during a 3am anxiety attack in November 2023
Real talk: I had 118 test scores but zero idea if I was ready for boards. Parents kept asking "are you prepared?" and I had no answer. So I built a regression model instead of sleeping. Predicted my scores within 3% accuracy. More importantly? Went from constant panic to actual data-driven study plans.
I was in 12th grade and freaking out about board exams. I had 2 years of test scores but no idea if I was prepared. Instead of panicking, I decided to use data science to predict my likely scores and identify exactly where to focus my study time.
The result? I built a predictive model that was 96.5% accurate, reduced my anxiety from 8/10 to 4/10, and helped me score 3% higher than my prediction by targeting weak areas identified by the data.
Key Finding: Based on correlation analysis, each hour of focused study correlates with +3.2% improvement. Adjust your study time below to see projected improvements.
✓ This schedule is sustainable and balanced.
Uses linear regression with three weighted factors: recent performance (72%), improvement trend (18%), and mock exam scores (35%). Validated against actual board results with 96.5% accuracy.
Tracked 118 tests over 2 years including weekly quizzes, monthly tests, quarterly exams, and mock boards. Each data point includes score, preparation time, sleep, and stress levels.
Analyzed relationship between study hours and score improvements. Found strong correlation (r = 0.68) showing each focused study hour yields approximately +3.2% improvement.
