Help on how to clear most GMAT in 10 days? :(

Hi, I had given my GMAT a month back but could not get through it.. The deadline to get into the university I desire is January 31st and my GMAT is on the 27th.. I know it is impossible to get a 700 in 10 days but I can still put in efforts.. Can someone please help me out? If I practice intensively...
