Editor's note: Not drowning in debt? Have $1,000 to put to work? TheStreet.com senior correspondent and You're So Money author Farnoosh Torabi checks out foreign currencies.Senior year of college my finance professor decided to shift gears from studying the Capital Asset Pricing Model and introduce us to the wonderful world of currencies.

Besides, back in 2001, investing in the U.S. dollar was the way to go for the most part. Why bother to learn the math? Our currency ruled. That was then.

But it's not too late, experts say. With the world's currencies strengthening, there are countless opportunities to make money, so that's how I'm going to "play $1K" this time: currency exchange.
