JavaScript test for Android
Have had two run throughs and scored 0% apparently each time. Since I know at least some of my answers were correct this looks like a bug. Also there doesn't appear to be any feedback given on what you got right or wrong.
by Q####:
Filled with pop-ups. Had ads take over the screen 6 times during the test. I missed some questions but it doesn't show you what you missed so there's no way to learn from this app.
