Hello OMBA students!

I currently have two tools for Blackboard Grades:

1. The OG Grade Calculator, which will calculate your grades in Blackboard and provide a percentage (your grade divided by the total). The grades will be displayed in a pop-up on the screen.
2. The newest tool CSV Grade Export will automatically export your grades into an organized CSV with 3 columns (Your Points, Max Points, and Item name). The item name is in the format "Wk 1 Team Assignment | Six Steps to Solving a Problem | Due Tuesday".

Blackboard CSV Grade Export (1/31/24):

This is my latest tool that will export all your grades into a downloadable CSV file. Find the code snippet above, and follow the same process as described below under "How to install".

v3 BETA update (10/29/23):

I have a new version that will provide the grades separately for each category (Knowledge Checks [20%] and Assignments [40%]).
It is currently being tested, and is in BETA (not yet ready for release). You can download from here.

v2.1 update (10/24/23):

This version includes calculation of the latest Group Assignment (Week 3-6 Team Assignment). I would recommend that you create a separate bookmark for this version since future assignments may or may not break the functionality. The prior versions that I created should work for the entire MOD.
Download it from this page: https://gist.github.com/nsina/b9ce5cafd2879deff8fcc817eaa6bba8

v2 update (09/29/23):

I've made some updates to the code. You can now use the same code snippet for all major browsers.

How to install

1. Create a bookmark in your browser. It can be a bookmark of any page. The tool works in all major browsers.
2. Copy the code from above (starting with javascript:). You only need the latest version v2
3. Go to your browser and edit the bookmark and replace the URL with the code snippet you just copied.
4. Go to the Grades page on Blackboard and open the bookmark. Remain on the page when you click on the bookmark.
5. Check your grades!

Safari

Apple requires additional steps to allow JavaScript. Follow the steps here or below.

1. You will need to enable the Develop menu. If you don’t see the Develop menu in the menu bar, choose Safari > Settings, click Advanced, then select “Show features for web developers.”
2. Open the Develop menu, and select the option "Allow Javascript from Smart Search...".
3. Now you can continue with step 4 from above instructions.

This is really cool! I love how simple it is to implement! Thanks for sharing it with us!
