To convert your GPA, you will need to:
1. Find out what the highest possible GPA is at your school.
2. Divide your GPA by the highest possible GPA.
3. Multiply the result by 4.0.
For example, if your school uses a 5.0 scale and your GPA is 4.5, you would calculate your 4.0 scale GPA as follows:
4.5 / 5.0 = 0.9
0.9 x 4.0 = 3.6
Your 4.0 scale GPA would therefore be 3.6.
Note that some colleges may have their own GPA calculation methods, so it is important to check with the admissions office of each college you are applying to to see how they calculate GPA.
