Grading Systems Explained

Standard Letter Grade Scale

A90-100%

Excellent performance, superior mastery

B80-89%

Good performance, above average

C70-79%

Satisfactory performance, average

D60-69%

Minimal passing performance

FBelow 60%

Failing, does not meet requirements

Plus/Minus System

Many schools use a plus/minus system for more precise grading. This typically adds ± modifiers to letter grades, allowing for finer gradations in performance assessment.

A+ (A Plus)97-100%
A93-96%
A- (A Minus)90-92%
B+ (B Plus)87-89%
B83-86%
B- (B Minus)80-82%

Note: Grading scales vary by institution. Always check your school's specific grading policy.

How Test Scores Impact Your GPA

Understanding Grade Points

Letter grades convert to grade points for GPA calculation. An A typically equals 4.0, B equals 3.0, C equals 2.0, D equals 1.0, and F equals 0.0. Your test scores determine letter grades, which then affect your overall course grade and GPA. A single test can significantly impact your final grade, especially if it's weighted heavily.

Weighted vs Unweighted

Some schools use weighted grading where honors or AP classes add extra points (A = 4.5 or 5.0 instead of 4.0). This means test scores in advanced classes have greater GPA impact. Unweighted systems treat all classes equally regardless of difficulty level. Check with your school to know which system applies.

Test Weight in Final Grades

Teachers assign different weights to assignments. A final exam might be 30% of your grade while homework is only 10%. Calculate how much each test affects your final grade by multiplying the test score by its weight percentage. For example, scoring 85% on a test worth 25% of your grade contributes 21.25 points to your final percentage.

Tips for Improving Test Scores

Before the Test

  • Start studying at least a week in advance, not the night before
  • Break material into smaller chunks and study in focused sessions
  • Practice with old tests or sample problems when available
  • Form study groups to review difficult concepts with classmates
  • Get adequate sleep the night before instead of cramming

During the Test

  • Read all instructions carefully before starting
  • Answer easier questions first to build confidence
  • Budget your time and don't spend too long on any single question
  • Show your work on math problems for partial credit opportunities
  • Review your answers if time permits before submitting

Frequently Asked Questions

What is a passing grade?

Most schools consider D (60-69%) the minimum passing grade, though some require C (70%) or higher. College courses often require C or better to count toward your major. Graduate programs typically need B- or higher. Check your institution's specific requirements.

How do I calculate what score I need on a final exam?

First, determine what final grade you want. Calculate your current grade without the final. Multiply your desired grade by 100, subtract your current grade times its weight, then divide by the final exam's weight. For example, to get 85% overall with 75% current grade (70% weight) and final (30% weight): (85 × 100 - 75 × 70) ÷ 30 = 108.3% needed (likely impossible, showing you need extra credit or curve).

Do all schools use the same grading scale?

No. While the 90-80-70-60 scale is common, schools vary. Some use 93-85-77-70, others use plus/minus systems with different cutoffs. International schools may use different scales entirely. Always verify your school's official grading policy in the student handbook or syllabus.

Can I improve my grade after a bad test score?

Yes, but it depends on the test's weight and remaining assignments. If the test is only 10% of your grade with 90% remaining, recovery is easier. If it's 50% with only 50% left, you'll need near-perfect scores on everything else. Talk to your teacher about extra credit opportunities or test retakes.
