isComplete = mathTotal >= 25 ? true:false;

That is what I used -- I don't think you need the parenthesis and it may reject the answer because it asks to assign true to isComplete and not Yes.

Hey Deniz,

It took me a minute to get this one too! It takes a ternary operator because you are evaluating the condition of isComplete as true or false. Your 3 operands being isComplete, the true result, and false result. The full explanation is in Video 3 under More Operators beginning at 2:52.

Hey Travis,

i went back and watched the video adding

isComplete = (mathTotal = 25) ? YES:NO

but i can't seem to get the answer right.
