How does your IB school determine Predicted Grades?

How does your IB school calculate PG’s? Our school makes them seem more like progress grades and they change as work is turned in, which is not good for applying to US colleges in the fall. Does anyone know if these are required for the Common App? I am a US student going to school internationally and my school has told me that on the International Common App school report forms, they require these, but I do not want mine to go out as they are not my final predicted grades. Thank you for you help.

US schools will ask for your transcript, and the school will send it whenever you apply. For regular applicants, a mid-term report is also generally required. No need for you to list anything on the common app (including GPA, as most schools will recalculate IB GPA by looking at your transcript regardless).
