For every five hours of studying combinatorics-type questions,
the average GMAT student increases their chances of being able
to correctly answer a question type that is found only on the
very difficult end of the GMAT spectrum. Meanwhile, the same
student will have to compute hundreds of basic computations
without the aid of a calculator. For students who know how to
quickly do these computations, they are rewarded with extra
minutes that can be spent double-checking their work and
critically thinking about whether their answers make sense. As
BenGMAT Franklin might say- a second saved is a second earned on
the GMAT… but it doesn’t matter if those extra seconds come from
being faster at doing combinatorics questions or quicker at
computations. So check out these five math tricks, learn the
ones that you like, and practice them daily to give yourself
some extra time to finish off that 37th and final quant
question. Note: like everything else on the GMAT, being able to
do something and being able to do somethi
