What's the difference between GPA and CGPA?

GPA (Grade Point Average) measures performance in a single semester, while CGPA (Cumulative GPA) averages performance across all semesters or an entire academic program.

How to calculate percentage from GPA?

To convert GPA to percentage: Percentage = (GPA ÷ 4.0) × 100. For a 3.5 GPA on a 4.0 scale: (3.5 ÷ 4.0) × 100 = 87.5%.

How does SAT scoring work?

SAT scores range from 400-1600, combining Evidence-Based Reading & Writing (200-800) and Math (200-800) sections. No penalty for wrong answers.

What is a good ACT score?

A good ACT score is 24+ (75th percentile). Top scores are 30+ (93rd percentile), while 20-23 is average. The maximum composite score is 36.

Frequently Asked Questions

How do I calculate my GPA manually without a calculator?

To calculate GPA manually, list all your courses with credit hours and grades. Convert each grade to grade points (A=4, B=3, C=2, D=1, F=0), multiply by credit hours, sum all grade points, then divide by total credit hours.

What's the difference between weighted and unweighted GPA?

Unweighted GPA uses a standard 4.0 scale where all classes are equal. Weighted GPA gives extra points (usually 0.5-1.0) for honors, AP, or IB classes, allowing GPAs above 4.0 to reward more challenging coursework.

How do SAT scores convert to percentage?

SAT scores don't directly convert to percentages. A 1200 SAT score represents approximately the 75th percentile, meaning you scored better than 75% of test-takers. Percentile, not percentage, is the meaningful comparison.

What GPA do I need for scholarship eligibility?

Most merit-based scholarships require a minimum 3.0 GPA, but competitive scholarships often require 3.5+. Some specialized scholarships may accept lower GPAs with strong extracurriculars or essays.

How do I calculate my final grade if exams are weighted?

Multiply each component (homework, quizzes, exams) by its weight percentage, sum these products, then divide by total weight. Example: Homework (20% weight × 90% score = 18) + Exam (80% weight × 85% score = 68) = 86 final grade.
