This post has been long overdue. I have published my first Windows Phone 7 app last January. Ever since, I wanted to share more information about the app. It is called GPA & Grade Calculator also known as GGCalc in my house.
My wife, Ania, is a college student who had a need to keep track of her grades and calculate her GPA. She asked me if I could write an app that could help her out. I agreed to take on the challenge. Considering that it was my first WP7 app and that I had never done any Silverlight or WPF development before it was an ambitious undertaking. After 6 weeks of development and testing it was finally published on Marketplace. Ania played a crucial QA and user role. Her non-developer background helped out in bringing a different perspective to the project which made the app more user friendly. Ania recorded a demo video of the first release.
Marketplace and usage performance
Since the initial release in January, I have released an update in April that has addressed some bugs as well as introduced many new features the users have requested. The app has done quite well in Marketplace. It has been ranked in top 10% consistently with 3669 total downloads in the first 5 months. As you can see on the graph it averaged between 20 and 25 downloads a day.

| Number of daily downloads |

| Number of daily runs |
Ad performance
The high Marketplace ranking may be attributed to the fact that GGCalc is free and ad supported. It uses pubCenter ad framework from Microsoft.
Looking at the Impressions (the number of times an ad has been seen by a user) graph we can see that the number of impressions had been on the rise from the release in January all the way through May.

| Number of impressions over time |

| Revenue over time |

| Revenue per thousand impressions - eCPM |
GGCalc has surpassed all Ania’s and my expectations from the user adoption rate perspective. The goal was to get familiar with WP7 platform and in the process maybe even create a useful app. I we have accomplished the mission.

To calculate your GPA, you need to know your grades. The rubric is
BalasHapusA=4 points
B=3 points
C=2 points
D=1 point
F=0 points
You can also calculate through this fsu GPA Calculator.Add up all your points according to the rubric, and divide it by the number of classes you have.
Example: I have 6 classes; 5 A's and 1 B. That is 4+4+4+4+4+3. That equals 23. Since I have 6 classes, divide 23 by 6, which is 3.83. So that means that 3.83 is my GPA. I hoped this helped!
The only GPA that universities care about is from high school- grades 9-12. It's usually calculated after each semester, when the final grades for that term are assigned.
There will also be a GPA for university, but that one doesn't matter as much as actually getting a degree unless you want to go to a post-graduate school.
College GPA calculator allows you to easily calculate your grade point average. GPA is calculated by dividing the total amount of grade points earned by the total amount of credit hours attempted. Your grade point average may range from 0.0 to a 4.0.
