In eLitmus, we are allowed to get 25% of attempted questions wrong without penalty.
Maybe 1 of your answers was incorrect, that is why you got negative marking.
Since you attempted 2, allowed incorrect is 25% of 2, which is 0.5. But your incorrect is 1. So you get penalty only for mistakes outside of 25%, which in this case is 0.5
So
+10 for 1 correct answer
-2.5 penalty
Thus total is 7.25
