Each school district in the nation may have their own way to calculate GPA, or weigh classes. As an independent homeschooler, you get to determine your own policy on calculating grades. I encourage you to do it the easy way. A different method won't give a dramatically different GPA, and so choosing the simple method of how to calculate homeschool GPA makes the most sense.
Besides GPA, there is a lot to learn about high school grades, credits, and transcripts. Let me teach you in this free class. Click to register: A Homeschool Parents Guide to Grades Credits and Transcripts Webinar
Is this method of calculating your GPA respected by the college board? & does the method hold in either Country or State ?
I think you may be overthinking this a bit. Here's the truth - all school districts across the nation have their own way of calculating a weighted GPA. I don't recommend using a weighted GPA, and this is the simplest method to calculate GPA that I have seen. The College Board does not need to approve your GPA, they are used to seeing all the different policies that schools across the nation have. Each country, county and state may have a policy as well. As an independent homeschooler, you get to control the policy for your homeschool. I suggest that simple is best. Colleges have told me that they do not like weighted grades, because it makes it more difficult for them to assess applicants. Unless your college or your situation requires weighting grades, I don't recommend it. As independent homeschoolers, we get to choose our own policy.
GPAs are acceptable to colleges, and many will require them if they are not included. I believe that parents really NEED to create a GPA, so that the student can earn scholarships. It's helpful to create course descriptions describing the class and the expectations, so colleges will know how you calculated the grade in each class.
Each public or private school can have their own method for calculating the GPA, but this is a standard format for GPA calculation. I do not recommend weighting grades, as explained in this blog post: https://www.homehighschoolhelp.com/blogs/why-i-do-not-recommend-weighting-grades
All teachers have a possible bias, and this blog post explains more:
I hope that explains everything!
If you are a homeschooling parent then YES you can calculate a GPA with no assistance. There is only one exception: if you are not homeschooling that class. If the class is accredited by a high school or college you can't - I mean if the student is taking a PE class in high school, a dual enrollment class at community college, or a class from an accredited institution that is giving you a transcript.
Parents and teens loved the free convention classes last month! The response was so phenomenal in these courses, I have identified a huge need in the homeschool community, and I'm
