Hi ZMan40,
It's certainly possible that if you don't have an AWA Score, then a School might ask you to submit an additional writing sample (beyond the standard essay(s) that are a part of most applications), but it's also possible that the Schools won't care at all. As it stands, the only way to know for sure how an individual School/Program would respond to this issue is to contact that School directly and ask (and the School's Admissions Department would likely be happy to answer any questions that you have about applying).
1) Are you planning to apply to Business School sometime soon (in the next several months or later on - sometime in the next few years)?
2) If you're planning to apply soon, then what are the exact application deadlines that you are facing?
If you're just beginning your studies, then it would be a good idea to take a FULL-LENGTH practice CAT Test; you can take 2 for free at
www.mba.com (and they come with some additional practice materials). If you want to do a little studying first, so that you can familiarize yourself with the basic content and question types, then that's okay - but you shouldn't wait too long to take that initial CAT. That score will give us a good sense of your natural strengths and weaknesses and will help provide a basis for comparison as you continue to study. A FULL CAT takes about 3.5 hours to complete, so make sure that you've set aside enough time to take it in one sitting. Once you have that Score, you should report back here (or you can feel free to PM me directly) and we can discuss the results and come up with a study plan.
