How to convert IB scores to GPA and letter grade

At the end of Year of of the IB program in the UK, this is what my daughter has for her scores. She got a score of 41 on her mock exams. She is going back to the USA next year. Trying to do some research as to what each of these may be for a letter grade (I assume a 7 is an A+) and a weighted GPA. Are all IB courses weighted at 5.0 or just HL courses? Art and Biology are SL courses, but I think she ended up doing HL exams.

Reports summary

My daughter moved schools after her sophomore year. The first school was the US News #1 STEM public magnet school with a 0-100 grading system. We moved internationally for work, so the second was a German International School with an IB program that has a 0-7 grading system. We never knew what her 4.0 scale GPA was. Colleges admitted her anyway and gave her merit scholarships. The only glitch we had was our State Public U that had an automated system for scholarships based on self-reported data. An email to admissions cleared that up and she was also awarded merit.

My point is, don’t worry about it, the colleges figure it out.

Weighting of GPA is defined by the HS. Some don’t weight courses at all so I wouldn’t worry about that. If her future HS weights grades then you can discuss the particulars.

I’m sure google can pull up an IB to 4.0 GPA calculator.

This issue is that she will be transferring some/most of the coursework back to the states. She also has test scores and essay marks and the school she is going to is the one she was at before (so she already has an existing GPA and history). Some of the sites show an IB of 5 upwards of 91%. She’s also going to ask her English teacher how far off the mark she is for a 6 (she still has 3 weeks of school left).

That’s the bottom line. Colleges will figure it out. The new HS will probably only calculate GPA on its own coursework.

Is her new school an IB school?

No, she’ll be doing the AP Capstone Diploma program. She started in on it as a Sophomore. I think she’ll be taking 3 AP courses and exams.

She’s already taken her SATs and ACTs and will take subject SATs this fall.

OK, again I would not worry about it, and file it under it is what it is. This is what IB says:

If she’s not finishing IB her predicted IB scores will not matter at all.

While true, I interpreted that the OP was asking about transcript grades; many IB schools report grades using the IB scale.
