"How well do today's schools prepare for tomorrow's world?"

That's the question in a new report from the This group administers the Program for International Student Assessment to 15-year-olds in 75 countries. The goal is to find out whether they can use their math and science knowledge to answer a series of questions that measure skills needed for young people to make a contribution to the economy.

The results from the latest round of testing, released this week, show that students struggle across the board — in rich and well-educated countries; in countries that are poor and where it can be difficult for youth to get a good education. For example, 89 percent of the test takers in Ghana didn't achieve proficiency — and 24 percent of Americans failed, as well.

If you would like to test your own skill set, here are three sample questions:

Problem Solving: Traffic

Here's a map of a system of roads that link the suburbs within a city. The map shows the travel time in minutes at 7:00 a.m. on each section of road.

Question: Julio lives in Silver, Maria lives in Lincoln and Don lives in Nobel. They want to meet in a suburb on the map. No one wants to travel for more than 15 minutes. Where could they meet?

Mathematics: Charts

<strong>CD SALES</strong> — **CD SALES**

In January, the new CDs of the bands 4U2Rock and The Kicking Kangaroos were released. In February, the CDs of the bands No One's Darling and The Metalfolkies followed. The graph shows the sales of the bands' CDs from January to June.

Question: In which month did the band No One's Darling sell more CDs than the band The Kicking Kangaroos for the first time?

A) No month

B) March

C) April

D) May

Financial Literacy: Shares

<strong>GRAPHING SHARES</strong> — **GRAPHING SHARES**
