It is very hard to say. It depends on your ability. To evaluate your most likely score I will suggest you go to GMAC.com website, register and download GMATprep
software (which is free). There are two CAT tests. Just give the first one and see where you stand. Most people say the GMATprep is the most accurate indicator of your score compared to other softwares. Also accordingly you will know in which section you are weak so that you can focus on that area and boost your score.
Nobody dies a virgin, life screws us all.
