Number Scale

• The 4.0 number scale is the most universal. Colleges use it and many high schools do as well. The scale ranges from 0 to 4.0.
  
  

Percentage

• Other schools use a percent scale from 0 to 100 percent. When you consider applying for college and need to list your GPA or analyze whether your grades are good enough to apply to a specific school, you will need to convert your percent to an appropriate number on the 4.0 scale.
  
  

Letters

• Another form of grading many high schools adopt is a letter based system, with grades from A to F. Each letter represents both a percentage and a number on the 4.0 scale. You will need to convert your letter to a 4.0 scaled number for college purposes.
  
  

Conversion

• The conversion scale used by the CollegeBoard is as follows
  
  A+ or 97 to 100 = 4.0
  
  A or 93 to 96 = 4.0
  
  A- or 90 to 92 = 3.7
  
  B+ or 87 to 89 = 3.3
  
  B or 83 to 86 = 3.0
  
  B- or 80 to 82 = 2.7
  
  C+ 77 to 79 = 2.3
  
  C or 73 to 76 = 2.0
  
  C- or 70 to 72 = 1.7
  
  D+ or 67 to 69 = 1.3
  
  D or 65 to 66 = 1.0
  
  F or below 65 = 0
