Is this weird to you to hear, (a)"Did you know about this before you take the test?" as a native speaker?
The situation is that this person knew some tips for the test that you didnít.
Is it better to say (b)"Did you know it before taking the test" or (c)"Did you konw it before you took the test".
This is a question I got from one of my friend, I personally think there's not much difference between these...
