Is a 4.5 weighted GPA good?

It is generally considered very strong on a 5.0-cap weighted scale, but the definition of good depends on your school and your goals. Talk with your counselor for context.

Do all US high schools use this scale?

No. Some use +1.0 for Honors, some cap at 4.5 instead of 5.0, and some do not weight at all. Always check your school's grading policy.

Are AP and IB always weighted the same?

Usually yes — both typically receive a +1.0 bonus on common scales. A small number of schools weight them differently.

Do colleges use the weighted GPA?

Many colleges recalculate using their own scale, often unweighted, and then look at the rigor of your courses separately. Both weighted and unweighted numbers can be useful.

Weighted GPA Scale

A common reference for how Honors, AP, and IB courses are weighted on top of the standard 4.0 scale. Schools vary — always confirm your district's policy.

Common weighted scale

Percent	Grade Points	Notes
Regular A	4.0	Standard 4.0 scale, no bonus
Honors A	4.5	+0.5 over standard scale
AP / IB A	5.0	+1.0 over standard scale
Regular B	3.0	Standard 4.0 scale
Honors B	3.5	+0.5 over standard scale
AP / IB B	4.0	+1.0 over standard scale
Regular C	2.0	Standard 4.0 scale
Honors C	2.5	+0.5 over standard scale
AP / IB C	3.0	+1.0 over standard scale

Some schools use +1.0 for Honors instead of +0.5, some only weight courses on an approved list, and some apply weighting only when the grade is C or higher. Use this table as a starting point, not a universal rule.

Examples

All A grades in five regular 1-credit classes → weighted GPA 4.0.
All A grades in five AP 1-credit classes → weighted GPA 5.0.
A mix of two AP A grades and three regular A grades → (5.0 + 5.0 + 4.0 + 4.0 + 4.0) ÷ 5 = 4.4.
