Answer

The sentence is wrong.  Of course, you use a plural noun when you ask "how many", and when you ask "did you...?" the main verb is in its base form.

"How many marks/points did you get?"
"Did you pass?"
"What score did you get?"

Answer

I don't understand the sentence either.  The following word combinations are strange:  "How many score" and "did you passed?"  Sorry I can't help you.  I hope someone else can.
