This is something new
Every question has same marks/weightage..
SCWCD has 70 questions out of which 1 is for user survey[you cant findout which one].
So eventhough you answer for 70 questions,69 questions will be taken into account and percentage(Floor function applied on resulting percentage) will be calculated appropriately.
Ex:Answering 65 out of 69 results in 94%
