Hello, bidtreezl

Can you tell what exactly do you mean by improve speed and acuracy. Sorry, for me your question is a bit too general. Do u look for some tricks and new strategies?

My personal opinion is that the best way to improve speed is - practice... (of course after getting to know all the concepts first). Just like QuantCoach said.... only I would have put it on a fist place... It is like in anything what we do. How much time does it take for a professional chef to make a meal? Why is he so fast?
1. He knows what he is doing.
2. He did this for so long it became his second nature. He doesn't stop and think - "Oh, man, what do I cut next onions or carrots?"... and he moves are accurate and quick after many years of practice...

The same is with math...{Practice, reviews, practice, review - there is no much more to it).. Just my personal opinion

Do you keep error log with timer? What is the bottleneck, i.e. what slows you down?

Sorry for a lot of questions and not being much helpful. But hopefully I'll be able to help a bit more after your reply. :wink:

Thank you,

1) There are some conversions you just need to know as facts not as calculations. You can find them in my math study sheet through my signature.

2) When doing fractions multiplications/divisions, cancel any common factors from the denominators and the numerators first before multiplying.

3) When you deal with really large or small numbers like 100000 or 0.00007, use scientific notation. 100000 = 10^5, 0.00007 = 7 * 10^-5

4) Know common algebra products both ways in the equations. x^2-y^2 = (x+y)(x-y), and (x+y)(x-y) = x^2 - y^2

5) practice

6) practice, practice, practice.....


Thanks for these pointers...I will try to use them in my practice :-D

and http://gmatclub.com/forum/math-formula- ... 77949.html


Well, quant is difficult for me for the following reasons:

1. sometimes takes me up to a minute to even understand the question
2. may take up to another 2,3,4,5 minutes to come up with a solution, so I end up guessing alot of Q's (score takes a huge beating)
3. I make ALOT of careless mistakes under pressure

I do keep an error log. I do all math in a bound notebook and write notes in red pen for the questions I missed, which includes the time spent trying to solve it.

I think for the questions I miss I'm going to just do over and over again maybe like ten times. What do you think?

Also, do you think that the math on the real test is harder than the GMATPrep and MGMAT quants? My average score has been lower on the real test by about 7 points

I went through those threads. The timing strategies will be useful for me, but the other link with the formulas seemed over the top unless you're getting 51's in quant.

thanks!!
