In this video, Jess and Rich show you the best methods for simplifying Data Sufficiency prompts and translating equations into more helpful forms. They present two sample problems (pause the video at 00:21 and 4:10 to try them out for yourself), and then walk you through the most efficient way to arrive at the right answer.
Plus, Jess imparts a particularly helpful tip: when Statement I and II provide exactly the same info (even if it comes in a slightly different form!), the only two possible answers are D and E.
