You can check your answer in the
error log. If you marked the correct answer, it will be green, If you marked the incorrect answer, it will be red. (In desktop/web browser).
However, if you are using the Android app (I'm not sure about the iOS app), you will be able to see both your answer as well as the correct/official answer in two separate columns.
But if you want to check the correct answer in desktop, you can again open the question in a new tab.
Error log can be accessed from anywhere (you can see the link on any question/post page)
