Ok, my biggest problem on the GMAT is time. As I have an ADHD (and the GMAC denied my extra time request, because apparently, you can still have an ADHD, but if it isn't severe enough to impact your every day life, you don't fall under the ADA guidelines and therefore do not need extra time... i.e. i hate the gmac), I end up getting killed on the math section. I have been looking for ways to do calculations much quicker than what I am used to, and came across some books on amazon that teach "speed math." One book in particular, The Trachtenberg Speed System of Basic Mathematics," seems to teach a mucher "faster" math method.

Can anyone recommend a good book, or does anyone have any notes that teaches this speed math? They give some examples and the concepts/tricks seem AMAZING.

Thanks

I have a copy of this book

This book delivers what it promises. It'll be useful to you if have trouble multiplying, dividing, or need help finding square roots, or squares.

The approach in this book is good if you need help on working with large numbers. It's a real time-saver there but I haven't come across too many large numbers on the GMAT, and when I have they have mostly been solved by applying the right concepts.

Sometimes you do need to work with big numbers. Check out the link below

Get this book if not being able to perform calculations is whats holding you back but before you buy the book I advice you to sample it here
http://mathforum.org/dr.math/faq/faq.trachten.html

Maybe it won't be a bad idea to try this in some of your practice tests:
Solve as many questions as you can and when you start to run out of time, pick any answer choices on the remaining questions to get to the end of the section. See how this strategy works for you.

BTW, the opening of the book tells a little about Jakow Tractenberg, the founder of this system. He came up with this system while he was in one of the worst Nazi concentration camps and Hitler himself gave orders to kill him so everyday was like his last. He had no paper to write on there and he came up with all the techniques explained in this book by working everything out in his head!

Pretty amazing, huh?
