How much credit does an AP score earn?

Most US universities grant credit for AP scores of 3 and above, with 4 and 5 reliably earning credit. A typical exam awards 3 to 6 semester hours, though selective schools may require a 4 or 5 and grant fewer hours.

Does IB Higher Level earn more credit than Standard Level?

Yes. Most universities grant credit only for IB Higher Level (HL) subjects, usually at grade 5 or above, and award little or no credit for Standard Level (SL). HL courses are treated as roughly equivalent to a strong AP exam.

Is AP or IB better for credit?

It depends on the school and your scores. AP often grants credit at a single high score per subject, while IB credit usually requires HL courses. The tool compares typical grants, but only the university's official chart is binding.

Why do private universities grant less credit?

Selective private universities often limit credit to encourage students to take their own courses, sometimes granting placement (skipping a prerequisite) instead of credit hours, or requiring a 5 on AP and a 6 or 7 on IB HL.

Are these numbers official?

No. They are typical ranges based on common US policies. Credit awards vary widely by institution and even by department, so always confirm on the specific university's AP and IB credit policy page.

Students juggling AP and IB often want to know which one will actually earn more college credit. This checker compares typical credit grants for an AP score against the equivalent IB grade at public and private US universities, so you can weigh the two pathways with realistic numbers.

How it works

The tool uses common US credit policies. AP credit depends on the exam score and the institution’s minimum; IB credit usually requires Higher Level and a minimum grade:

AP:  score >= public-min ? typical hours : 0
     public-min  = 3 (often)      private-min = 4 or 5
IB:  HL and grade >= min ? typical hours : 0   (SL usually 0)
     public-min  = 5              private-min = 6

Typical full-credit grants are about 6 semester hours for a year-equivalent AP exam or an IB HL subject, scaling down for borderline scores. The tool then flags which pathway grants more for your inputs.

Example and tips

An AP score of 4 at a public university typically earns about 6 credit hours, while an IB HL grade of 5 earns a similar 6 hours — a near tie. At a selective private university the AP 4 may earn 3 hours or only placement, and the IB HL 5 may earn nothing until grade 6. The lesson: push for the higher score, prefer IB HL over SL for credit, and always check the specific school’s official chart before deciding.
