Quant Review:
So here are my thoughts on gmat prep test 1 and things to be learnt:

I spent around 2-3 hours this morning analysing my exam from last night. I know this is not the real Gmat, but I think from the past experiences this score is + or - 40 compared to GMAT. So my range is 620 <= GMAT Score <= 700.

The first thing I learnt while analysising is

"SEARCH BUTTON" in this gmat club. I found almost 95% of my questions that I got wrong here. AMAZING SITE. I LOVE THIS SITE, and ITS THE PEOPLE'S PARTICIPATION THAT MAKES THIS SITE THE BEST!!!!!!!!!

Hopefully many of you find it helpful.

1) Under Pressure DS. In time constraint and exam pressure, Dont know when to plug in vs when not to plug in values. Sometimes we can solve eqns and figure out the soln. So what is the way out. ALWAYS spend 10 seconds on re-writing the QUESTION. I used to do it when I solved

OG, hence I had a hit rate of 92%, but now in the exam I got 8 wrong. Not good!

So for example s,t are not equal integers:

rewrite: s ,t ==> {I}, s <>t

That is the first thing you need to write, before you get to the answer choices.

Easy to say here, but in the exam condition when you look at time left, you want to solve IT ASAP. PLEASE DONT DO THAT MISTAKE. Sit down and spend 10 seconds on

rewriting the question.

2) Under Pressure PS questions:

Silly MISTAKES Problems that I would have got in my sleep, I could not come up with a solution in the exam. I swore the "f" word like 20 times, and twice my wife came in to see what was happening. i was really pissed of on not solving one problem in 10 seconds because it was that easy. What happened? I spend 4 minutes on that problem. because of ego clash and getting irritated.

3) Wording Problems: You have to spend time in understanding what they really want. Is it 2/3rd of the distance left ,or 2/3rd of the entire distance. Spend a minute to understand what is been asked?

4) Number 0: Unique properties. 0 is divisble by every number? Now in the exam constraint, thinking ETS is very smart, I tried to out think them, and said hmm maybe they wanted me to think that, and not consider 0 as one of the choices, so I considered 0 which was good, but 0 is unique.

0 is even

0 is an integer

0 is neither positive nor negative

0 is divisble by every number

0 is a multiple of every number

Have I missed anything else with 0?

5) Need to understand clearly how decimals are termed: Hundreths digit is not the same hundreds digit. In the exam pressure I just forgot the difference. Also because there were not that many problems to practice on the decimals. Its like you have to know the terminilogy really well!

I probably lost around 5-6 questions in silly mistakes. So I am not feeling that bad.

New tricks that I learnt are:

1) A few things about mixtures, and decimals from this test.

2) External angles of triangle is sum of two interior angles. This seems to be tested more recently on the Gmat than before. I knew this property but forgot to apply it here in triangles.

Path forward:

1) Practice all DS questions from this site under timed constraints

2) Do Manhattan Tests: They had some excellent word translations problems. I did not do them under timed conditions, so now I am goign to do them under timed constraints.

3) Brush up on terminology and number properties.

With the above I am sure I will reach 49+ in Quant. That is one half of the battle.
