How IB courses are weighted
Most US high schools weight IB courses at +1.0, the same as AP. This applies to both Higher Level (HL) and Standard Level (SL) courses. An A in an IB HL Physics course earns 5.0 points; an A in IB SL Spanish also earns 5.0.
A few high schools differentiate HL and SL. If yours weights HL at +1.0 and SL at +0.5, mark SL courses as "honors" instead in the calculator above.
IB grade vs. letter grade
IB also reports scores on its 1-7 scale. US transcripts usually convert these to A-F before computing GPA. The common conversion:
- IB 7 = A+ or A
- IB 6 = A or A-
- IB 5 = B+ or B
- IB 4 = B- or C+
- IB 3 = C or D
- IB 1-2 = F
Your high school's official conversion is what matters for your transcript. Check there before applying the table above.
