You have a grid. A "move" on the grid consists of moving squares to the right and squares down. In case of exiting by a line, it continues at the beginning (left) of the same line and in case of ending a column, it continues at the beginning of the same column (above). Where should we start so that after moves we end up in a corner?

In an electronic game of questions and answers, for each correct answer the player adds points on the screen, for each incorrect answer points are subtracted and when the player does not answer, no score is added or subtracted. Each game has questions. Francisco played games and in all of them he obtained the same number of points, greater than zero, but the number of correct answers, errors and unanswered questions in each game was different. Give all the possible scores that Francisco could obtain.
