It's a good attempt but there's a problem with some of the answers, I'll go into those in a moment, firstly I want to say that while graphically it's not great, it does do the job and fits in well with the Newgrounds theme, the music is an okay choice and the ability to mute is nice, the reveresed flash image at the top is not a good look though, no need to have it reveresed, it just looks silly.
To be a helpful flash, it should give the user feedback about the review, stating why it is helpful/useless/abusive, sure it might defeat the point at the end but that shouldn't really matter if your attempt is to educate.
Now, onto the problems with the questions, I'll only do the ones that seem wrong.
1: This is a code for a game, you're right in it not being abusive but helpful/useless should be down to the person putting it in, so both helpful/useless should be right.
16: "u sux/u emo" or something along those lines is what it is, you've got useless down as the right answer but it should be abusive because it's directing an insult at the author and saying nothing about the flash.
18: Same as 1
There are 1 or 2 others that seem borderline but really, useless/helpful is down the the readers own judgment more than anything else.
There is also a bug at the end where after you click continue, it just repeats the score and nothing happens, so to play again, you have to refresh, making it very akward to replay.
