I'll try to help with the syntax, but the logic (what you need) is not crystal clear to me.
I think the IF statement logic is just a little mixed up.
When you have multiple if's together you don't need to provide the 'else' value in every line.
If(
question 1, true answer 1,
question 2, true answer 2,
question 3, true answer 3,
answer if all are false)
currently it looks like you have an 'else' answer for every question.
Basically you don't need the ", 0," after every line, but only at the end.
Secondly, you need to write the statement from top to bottom. i.e. Once it finds one correct answer it will use that, and not even check the rest.
