GMAT Ninja Quant Ep 7: Percentages

Do you struggle to translate a percentages question into algebra on the GMAT or the Executive Assessment? Have you memorized all the formulas and techniques but you're still missing more percentages questions than you'd like?

In this video, Harry -- a GMAT Ninja tutor -- will build your intuitive understanding of percentages so that you can tackle these questions with 100% confidence. In particular, he'll show you how to make fractions your best friend when you answer percentage questions under time pressure.
