Hi darshans,

This is an example of 'format logic', which is more of an LSAT concept than a GMAT concept. The logical equivalent of...

"If A, then B...."

is called a 'contra-positive'; in this case, it would be...

"If NOT B, then NOT A."

Are you studying for the GMAT right now or some other Exam (and if you are studying for the GMAT, then what study materials are you using)?

Hi Rich,
Thank you for your reply and explanation. I am studying for GMAT (just started), currently I am using OG-2015 and material available online. I am not sure about the source of above question, received it from friend around 1000 CR collection from multiple sources.

Regards,
Darshan

Hi Darshan,

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 take the GMAT?
3) When are you planning to apply to Business School?

GMAT assassins aren't born, they're made,
Rich

Hi Rich,

Thank you for your response, sorry for delayed response, I was stuck with some personal priorities.
I took the Full CAT scored 670 (Q50, V31), RC is current hurdle for me.
Below is what I am looking for:
1) What is your goal score? Min. 720
2) When are you planning to take the GMAT? Mostly by end of Sept (this month) or First week of Oct
3) When are you planning to apply to Business School? Planning to apply this year and join the B-School from 2018

I have 9.5 yrs of experience, will be looking for either Full Time or Executive MBA

Regards,
Darshan

Hi Darshan,

A 670 is a fantastic initial CAT Score; assuming that you took this CAT in a realistic fashion, you likely are already a strong critical thinker - so you just have to learn a bit more about GMAT content and the Tactics that you can use to score higher. Since the bulk of the missing points that you're after will be found in the Verbal section, we have to do a bit of analysis of that section of this CAT.

After taking each CAT, it's important to do a full review of the Exam - with the goal of trying to define WHY you got questions wrong. After reviewing the Verbal section of this CAT, how many questions did you get wrong....
1) Because of a silly/little mistake?
2) Because there was some verbal that you just could not remember how to do?
3) Because the question was too hard?
4) Because you were low on time and had to guess?
5) On how many questions did you "narrow the answers down to 2 choices" but still get the question wrong?

GMAT assassins aren't born, they're made,
Rich
