a lil about me: well i prepared for around 20-25 days and had to make the most of the time had. It was all studies and no work.
For CR:
OG does list some of the tricks if u see its explanation.
some really common traps that Gmat uses:
What i found was there are three kind of choices in CR
a) choices which are irrelevant and thus absurd
b) choices which seem to be relevant but are out of scope (Will get back to this)
c) the correct answer
just learn to spot these three choices and u are thru..
consider this example
A certain mayor has proposed a fee of five dollars per day on
private vehicles
entering the city, claiming that
the fee will alleviate the city’s traffic congestion. The mayor reasons that, since the fee will exceed the cost of
round-trip bus fare from many nearby points,
many people will switch from using their cars to using the bus.
Which of the following statements, if true, provides the best evidence that the mayor’s reasoning is flawed?
(A) Projected increases in the price of gasoline will increase the cost of taking a public vehicle into the city.
(B) The cost of parking fees already makes it considerably more expensive for most people to take a private
vehicle into the city than to take a bus.
(C) Most of the people currently riding the bus do not own private vehicles.
(D) Many commuters opposing the mayor’s plan have indicated that they would rather endure traffic
congestion than pay a five-dollar-per day fee.
(E) During the average workday, private vehicles owned and operated by people living within the city account
for twenty percent of the city’s traffic congestion.
The highlighted words are scope words i.e. they limit the argument.
it says the fee will be only on private vehicles, only vehicles that enter the city (nothing mentioned about public vehicles or vehicles that drive in the city ) do u get it. Moreover, the argument says MANY people will shift not ALL.
So a choice that deals will public vehicles, vehicles driving in the city will be out of scope, many a times u would miss these easy choices look out for them.
some important scope words:
1) Immediate: u are concerned with the immediate effect of a plan or a policy not the effect in long term
so if a choice says after 10 years the plan will be successful this would be out of scope.
2) Should means moral obligation
Next would discuss how i approached common CR questions ...would get back soon ,
Hope some finds this useful
cheers
