In Russia there's a platform called MESH that has online tests. Once I decided to create a semi-automated application that would solve these test.
After I finished the project I began testing it and it worked. Two weeks later the 'MESH' test system recieved some changes making my method obsolete. I'm probably not going to try remaking the application for the new test system since I myself have no use for it.
I've also commited a .odt file containing the explanation on how the program used to work).
