we experienced the same trouble
with good result in many practice tests, it it hard to believe
that all effort that both of us put generate "nothing"
Since I'm very poor at verbal. I can't give any much suggestion
But if you are not native speaker, I suggest go read
Honghu opinion on how non-native speakers can build
their strength in verbal. It is not just easy like native speaker
who improve verbal by brushing up their skill
For non-native , it is 10 times harder to improve this
but it is really worth to put an effort into it.
For quant , I believe in trying to finish any question as fast as possible
and this series of exponential work well for me
for "2" series, I can remember from 2^1 to 2^14
3 series '' '' 3^1 to 3^6
5 '' '' 5^1 to 5^5
If you can remember this well, when met with big number
I often can easily break it down such as 729 =3^6
16384= 2^14
and set of sin,cos,tan 30,60,37,53 degrees is a must also
In DS , when plug-in plug with
1. negative integer -3 -2 -1
2. negative non integer THAT more than -1 (I like to use -1/2 )
3. zero 0
4. positive non integer 1/2
5. positive integer 1 2 3
Don't plug-in if not necessary
and practice hard on limit time
I believe GMAT now having more asian people on their test-producing team
Many question that I met need more techniques to solve in limit time
you can use basic math to solve but it take 4-5 minutes
that's the basic that can help to lessen time on solving question.
