Hi all,
This forum has been and continues to be one of the best resources for me. I am taking my GMAT in 3 weeks time, and I got started on the Quant section today. I was looking through the forum for some good notes, tips and shortcuts that would help me brush up my math from school and university while also maintaining accuracy and speed - great notes by Slingfox, Target760, and of course the ever-resourceful GMAT Club Math Book.
As for shortcuts, I remembered something that I had learned way back when I was a kid - Vedic Mathematics. Thought it might be interesting to share that here, and also links to a few good sources:

OPTIONAL and would recommend to not spend much time memorizing them. Just thought it would be interesting, maybe even useful to you beyond the GMAT
Happy studying, everyone!
