First, only you can make yourself be a "loser" by setting up that mental comparison. I'm surrounded by people in my home town who have never even heard of the GMAT - even though some of them would probably score horribly on the GMAT, they don't consider themselves losers...and you're ahead of them.

Second, I've heard Kaplan lowers their test scores...makes their guarantee easier to prove I suppose. So your performance on actual GMAT will likely be a little higher.

But as for what to do, simply breaking down verbal vs math isn't enough. Are you performing worst in PS, DS, SC, CR, or RC? From there, you can pinpoint what areas to practice.

And stop taking practice tests lol: seems like you need to break the concepts down and figure out where you are weak, instead of broadly practicing questions.
