I'll give my 2 cents till someone comes in and shares his/her score.
Gprep-44 shows that you have some work to do on quant. That is the best indicator if there ever was one.
My suggestion is - don't try to map out your performances from different tests. The practice tests are for you to see what areas you are lacking in, can you perform well under timed conditions etc. It is important to know whether you have improved over the past few weeks, but try not to convert 1 test score into another or find other people's test scores for every test you take.
I know this is easier said than done and frankly, easier to say in hindsight. But, that is how it is. And for the record, I found GC quant tests to be really good - because they helped me identify areas where I needed to concentrate and not because I was scoring too good/bad on them.
