Should my parents change the grading system for my homeschool transcript to increase my GPA?https://www.prepscholar.com/sat/s/colleges/Hendrix-College-admission-requirements#:~:text=The%20average%20GPA%20at%20Hendrix%20College%20is%203.93.,to%20be%20at%20the%20top%20of%20your%20class.
Changing the A grades from 90-100 to 88-100 and the B grades from 80-89 to 76-87, etc. will significantly increase my GPA. For college, I am considering Hendrix College. I have just received my SAT results and my SAT, which no doubt will increase in a couple of years, exceeds their minimum. However, as you can see from the following web site, scroll down to Admissions Calculator, a 100 point increase in my SAT will not increase my chances of admission as much as 0.4 point increase in my GPA.



A 100 greater SAT increase my changes of admission by 10%. However, with the same GPA, a 0.4 point higher GPA increases my chances for admission by 22%.
