Hi sunnytiss,
If you take any of the Official practice CATs and/or the Official GMAT, you'll find that the 5 answers to DS questions are always the same 5 options. In addition, the 5 answers are all explained in each version of the GMAC Official Guide (for example, in the GMAT2020 book, you can find this information on pages 269 - 272).
The 5 answers to DS questions are:
A Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
B Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
C BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
D EACH statement ALONE is sufficient.
E Statements (1) and (2) TOGETHER are NOT sufficient.
Here's what those answers really mean:
A - The additional information in Fact 1 is enough on its own to prove that the answer to the question is always the SAME answer, but the information in Fact 2 can lead to different answers to the question.
B - The additional information in Fact 2 is enough on its own to prove that the answer to the question is always the SAME answer, but the information in Fact 1 can lead to different answers to the question.
C - The additional information in BOTH Facts is needed to prove that the answer to the question is always the SAME answer.
D - EITHER Fact 1 or Fact 2 is enough on its own to prove that the answer to the question is always the SAME answer
E - Individually, and together, the information in Facts 1 and 2 can lead to different answers to the question.
From your message, it sounds as if you are in the early phase of your studies. If that's the case, 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 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 take the GMAT?
3) When are you planning to apply to Business School?
GMAT assassins aren't born, they're made,
