Unfortunately, Google KickStart does not provide an easy way to see all the problems you have finished. You have to check the problems one by one. Also they do not provide an easy way to see stats about all the problem on a single page. You have to check the stats contest by contest. Finally, their API is extremely inconvenient to extract data from. You will need to reverse engineer the API responses. As a result, I put together this page to help track the problems you completed and to give an idea which problems are harder.
