Summary
The content focuses on strategies for tackling unconventional graphs and data interpretation questions on the GRE, emphasizing the importance of maintaining composure and applying logical analysis.
  • Unconventional graphs on the GRE can range from slightly unfamiliar to completely novel, requiring test-takers to adapt quickly.
  • The GRE will provide all necessary rules for interpreting these graphs, making careful reading and application of known graph-reading skills crucial.
  • Examples include interpreting graphs that show relationships between different variables such as volume, pressure, and temperature, or analyzing sales data and currency exchanges.
  • Estimation and a general understanding of mathematical concepts are often sufficient to answer questions correctly, even without precise calculations.
  • Maintaining a level head and not being intimidated by unfamiliar graph formats can give test-takers a significant advantage.

Frequently Asked Questions

FAQ: In the atm and pressure problem, I don't understand how the percent increase was 50%. Can you explain a bit more?

A: So, we're increasing from 50 to 75.

By our percentage change formula, we take the "change" and divide it by the original value.

So, our "change" is:

75-50 = 25

We then divide this by our original number -- 50:

25/50 = 1/2 = 0.5

Finally, we multiply by 100 to turn it into a percent:

0.5 x 100 = 50% increase
