Help with GPA question

Hoping someone can help me out. Summer term I had a cumulative gpa of 2.54. Last term I retook some classes and received a 2.50 gpa for the term. My cumulative gpa dropped to 2.53 Why would my cumulative gpa drop if I passed both the classes I took? Can't seem to figure this out. Here I am thinking that by retaking these classes to get higher grades it would help improve my gpa but instead it dropped a point even with me passing.

Because you started with a 2.54 GPA and dropped to a 2.50 GPA, so it dropped your overall from a 2.54 to a 2.53.

In order to raise your GPA to a competitive level, you need to try to get straight A's in whatever classes you have remaining, as well as re-taking a couple other classes (check with your school to see how many re-takes are allowed, however) and aim for a 4.0 semester GPA. This will help raise your overall GPA.

Let me enlighten you on how a gpa works.

Each class is worth credits (you obviously know that). For each credit you are awarded quality points as dicateted by the grade you recieve in the class.

For example and A is worth 4 quality points per credit, a B worth 3 quality points, a C worth 2 quality points... etc etc

So if you get an C in a 4 credit class, A B in another 4 credit class and a C in a three credit class you have a total of 26 quality point, to find your gpa you simply divide that number by the number of credits you've taken in this example, 11. Gpa for the example is 2.36.

Now, if the semester previous to this you took say, 8 credits and got a 3.0, you would now have 2.63.

Because your new gpa is lower than your last gpa your gpa goes down to reflect the new gpa.

It doesn't matter if you pass or not, it's about the ration of quality points to credit attempted.
