To Improve CR, is it suggested to do untimed first and focus on accuracy and process? and then time myself, or start timing from the start? (currently at 54th percentile)

Yes. You can start un timed but 80% of all your practice should be timed so don’t spend two months with five minutes per question. Instead spent a few days and figure things out and then tighten the timing. Or whatever works for you… it’s not like there is a single way or a single course or single book. People have gotten high scores with many resources and many strategies. You just have to recognize when the strategy may not be working for you

Re: Study Plan Q&A Chat [#permalink]
Hey bb! thanks. I was wondering if there is a forum or thread that is active and does ESR analysis? I am trying to jump from 660 (Q48, V33) to atleast 700 in a month or two (CR weakest and DS in quant). I understand this is a very specific ask, but maybe there is someplace I can get some feedback on my ESR?

Hello!


A box contains n shirts, of which 60% are white in color. Three out of every four non-white shirts have a tailoring defect. What percentage of white shirts do not have a tailoring defect?

(1) If one shirt is selected at random from the box, the probability that it will have a tailoring defect is 0.5
(2) The probability that a shirt with tailoring defect will be white in color is 2/5


Can anyone help me understand this?

Re: Study Plan Q&A Chat [#permalink]
Good question! IMO D as well.

We know that 60% of n shirts are white in colour. So 3n/5 shirts are white. And 2n/5 shirts are non-white.
p(non white shirt with tailoring defect) = 3/4
So total non white shirts with tailoring defects are 3/4*2n/5 = 3n/10.

Statement 1: If one shirt is selected at random from the box, the probability that it will have a tailoring defect is 0.5
So total defect shirts(white+non white) = n/2. Out of these n/2 shirts defect shirts, 3n/10 shirts are non white defects. So shirts with white defects = n/2-3n/10 = 0.2n shirts.
% of white defect shirts: (0.2n/n)*100=20%

Statement 2: The probability that a shirt with tailoring defect will be white in color is 2/5
White shirts=3n/5, Non white shirts=2n/5
Non white shirts with defects= 3/4*2n/5=3n/10

Given: p(white shirt with tailoring defect)=2/5
# white shirts with tailoring defect/All shirts with tailoring defect = 2/5
Let # white shirts with tailoring defect=a
a/(3n/10+a)=2/5.....(Non white shirts with defects=3n/10)
5a=6n/10+2a
a=2n/10
% of white defect shirts: (0.2n/n)*100=20%

Thus, option D. Hope this helps!

Should be D.
You can set up a matrix as follows:
W NW T
D
ND
T
And fill in with the information given in the problem, and you will see that each statement is individually sufficient

LSAT is the best. There is also this book called Superprep by LSAC that helps too. It has detailed explanations of the questions given. Analysing and then comparing where exactly you went wrong might help you push past certain barriers.

Re: Study Plan Q&A Chat [#permalink]
best advise would be to take egmat or ttp, you will be able to wrap up whole sc in 10 days..By whole I meant almost all major concept, and rest time you can devote to practice
