I have a question about my gpa?

When you get to be a senior and apply to college, you can simply enter your GPA on the 100 scales into the Common App. All applicants have the option of picking the scale their high school uses.

It is not uncommon for high schools especially private boarding schools to quote grades on a 100 scale and it makes it easier for the admissions office as well.

As you do your research, you will see that have a borderline grade average of 89.5 is open to a lot of interpretations. Even if you had a 90.00% that would be open to interpretation as well because some charts say this is a 4.0 while others say this is 3.7 and others still say this is a 3.6. I tend to think an 89.5% is a 3.58 because if 4.0 is the theoretical max, then 89.5%X.04=3.58

I personally think that colleges who evaluate applicants on a 100% scale treat these students more fairly because there is no grade inflation bias in the reported 4.0 scale.

With many public schools, there is a lot of grade inflation built into the 4.0 scale. For example, if your HS treats the grade A+, A, A- the same by giving a 4.0 for each of those then 3 different caliber students can have the same UWGPA from the school. Student A might have mostly A+s, Student B mostly As, and Student C mostly A-s, but on their transcript they all have 4.0s. And if these same 3 students take 10 AP classes, and they all receive the same grades in them, then their WGPA might all be the same 4.50 WGPA. The admissions officer has to then figure out which of the 3 should be accepted even though they have the identical transcript. What is clear from my example is that 2 of them have grade inflation and 1 really bad grade inflation.

How this gets out of hand is if the Student C takes 12 APs and gets mostly A-s and the better student A takes 6 APs and gets A+s. On their transcripts, Student C might have a 4.62 WGPA and Student a 4.31 WGPA. So if you don't understand the inherent grade inflation bias your gut instinct is to say that Student C is the better candidate because their WGPA is higher evidenced by them challenging them more with taking more APs. But the reality is that they never do enough quality work to get an A or an A+, they just take as many APs to improve their class rank and make it seem they deserve to be valedictorian. Whereas the Student A is always top of their class and only takes 1/2 as many APs as it allows them to keep their A+. If I were the Admissions Officer, I'd accept student A over B and put C on the waiting list.

At schools that use a 100.00 pt scale, it's easier to see who the better student is.
