Some high schools choose to grade students on a 5.0 scale rather than the typical 4.0 scale for certain classes. A student typically receives 5.0 grade points for a class if they earn an "A" grade in an Honors, Advanced Placement (AP), or International Baccalaureate (IB) class and receives an extra point added to the non-weighted value for each lower grade (i.e., a B in an AP course is counted as 4.0, rather than 3.0). An "A" grade in a non-Honors/AP/IB class still earns 4.0 grade points.
While the system described above is a common weighting system for GPA, there is no single standard for weighting secondary school grades. Different schools have different weighting practices, while others do not weight grades at all.
Please fill out the GPA section to the best of your ability using the scale your school provides, and select "School doesn't calculate" in the appropriate fields if your school does not provide either an unweighted or weighted GPA.
