Click on the Google Docs link below and download it as a .xlsx spreadsheet file. If you don’t have MS Office, you can download Kingsoft Office for free.
Enter your progress for each challenge in the Progress column and it will give you the corresponding point towards your goal of 553 and total them at the top so you can see how close you are.
All the challenges are alphabetized per category. This was built using the XBOX 360 platform.
Special thanks to CountKarloff for the upper levels for the grinder.
