Hi Neweywest,
Welcome To the Gmat Club

Well Dear first of all dont feel tensed..Keep urself cheered up...

First of all i will say dont go by Kaplan Scores there scoring is actually bit different then Real GMAT.
Have u tried any GMAT prep? try giving one if u havent yet..
U r already in the line of 650 score dear so Just keep ur spirit high..I will say try to find out ur mistakes,the questions in which u r actually getting wrong...revising the strategies and solution for those question will surely help to increase ur score..
In one line i will say Worrying too much wont help u increasing ur score!!
There are many guys here in the forum who had confidence and scored above 750 + just within 30 days..
All u need to do is try to find the main mistakes ,which part of syllabus u r going wrong and then work on it..
u will surely cross the ocean

All the Best
