PowerPrep scoring... higher Q raw score on test 2 but lower overall score? :(

[StatsNerd]

Explain this...

 

Two weeks ago I took the first PowerPrep test and scored 160V/152Q. Today I took the second PowerPrep test and scored 161V/147Q (which was hugely upsetting considering how much I've studied Quant over the past 2 weeks ). Anyway, as I was analyzing my raw scores I noticed this:

 

PowerPrep 1 Quant raw score = 25/40

PowerPrep 2 Quant raw score = 26/40

 

So I got a higher raw score on test 2 yet somehow still scored 5 points lower?!? So then I looked at the breakdown between sections and noticed that while with test 1 is pretty even (13 correct section 1, 12 correct section 2), with test 2 I did far better on the second section (9 correct section 1, 17 correct section 2). So... assuming the Powerprep tests are adaptive, do you think it was my very poor performance on the first Quant section that made my overall score that much lower for the test I just took?? Even though technically I had a higher raw score? 

 

I'm taking the GRE Monday and this was a blow to my confidence. :/ I guess doing well on the first section of quant and/or verbal is really important, huh?
