hello subhasis, don't lose heart. first of all, try to do questions under untimed condition bcoz if you are really weak in basic CR, its of no use to rush and mark all answers wrong.The most important thing is you should first make a strategy to attack a question, you can just read the strategy section of this wonderful forum(BTG) and can follow some tips and suggestion to improve your critical reasoning skills. Also, I have heard about a book called Powerscore CR bible, though I haven't tried it myself, which is said to be best book for CR.Above all you should be courageous to fight this demon called GMAT...All the best !!

Hello

I think the CR part is where even the native speakers also have problem, so don't worry about that.Infact this is the part which drives nuts to every test taker

I have not given the test yet but I am not the beginner also.

When I started I also faced the same problem like you are facing. But I have been consistently doing PowerScore CR Bible. This book is really having some great concepts to tackle questions.

As far as OG-11 is concerned, the questions are not topic wise and not proper concepts are there to learn from.

OG-11 is good for practise and not for learning.

Hope this helps

Thanks a lot for your suggestions. I have started with PowerScore GMAT Critical resoning bible.

The problem of mine, is I generally understand the question stem also able to distinguish between conclusion and evidence.

But while choosing answers, i always choose so called "out of scope" answers.

Valid answer sometime appears "Out of scope" for me.

Hoping,PowerScore bible will help.

Hello,
I think all Questions in CR,they have some kind of out of scope Answers which although at first may seem very obvious to anybody.

The key is to read very closely.As you start practicing more and more you will get acquainted.

The best way to get rid of Out of Scope answer is to ask your-self is something about this is really given.
Or if including this new info really worth of Strengthening/Weakening the argument.
