Hi emin777,
You posted this message in another forum on this site, so I've copied over my response from there:
Since it sounds like you're just beginning your studies, then it would be a good idea to take a FULL-LENGTH practice CAT Test; you can download 2 for free from
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 4 hours to complete, so make sure that you've set aside enough time to take it in one sitting. Once you have those scores, you should report back here and we can come up with a study plan.
I'd like to know a bit more about your timeline and goals:
1) What is your goal score?
2) When are you planning to apply to Business School?
3) What Schools are you planning to apply to?
Based on what you've described about your plans so far, I can see a couple of potential issues:
1) Your list of study materials is 'book-heavy', but taking a book-heavy study approach might not be enough to help you to hit your goals. Many Test Takers who use a book-heavy study approach tend to get 'stuck' at a particular scoring level, so you will probably need to invest in some additional non-book materials.
2) It sounds like you're considering putting in heavy study hours each day, week after week, for several months. That type of high volume studying can sometimes lead to 'burn out' - and that is a consequence that you'll want to avoid.
