The queues are becoming too difficult to handle manually. So I'd like to do it on a spreadsheet.

I've created a separate sheet on the Reviews Spreadsheet.  The main sheet is called Projects. The queues sheet is called Queues. (It looks like it's not possible to link directly to a sheet. To get to the Queues sheet, click the Queues sheet tab at the bottom.) I've reproduced the queues as best I could. If I've made a mistake let me know.

The queues are listed vertically. To add yourself to a queue, right click on the row number (at the far left) of the empty line at the bottom of a queue and select 
"Insert 1 above." Then enter your name.

Please limit yourself to one queue at a time.

Please don't put yourself into an Extra credit queue until you already have credit for the main part of the project.
