Up To Date Quant Percentiles?

Hey All: My test is in 8 days. I took a GMAT Prep test yesterday and scored a 720 (Q43 V 46). The software said my quant was in the 61st percentile but the mba.com website says it's only 55th. Is this going to drastically alter my score? Will I need to score 44/45 on quant to stay at 720 on test day...
