They’re feeling the wrath of the math.

Student-loan interest rates could soon double — from 3.4 percent to 6.8 percent — and the people who have to pay it and some elected officials aren’t too happy about it.

“I’m a student with over $11,000 in unsubsidized and subsidized federal Stafford loans,” Alyssia Osorio, 22, a senior at City College, said yesterday. “Education is a right, not a privilege.”

At a Hunter College demonstration yesterday, Osorio and fellow students — along with Democratic Reps. Carolyn Maloney, Charlie Rangel and Gregory Meeks — protested the hike, which is scheduled to go into effect tomorrow.

“This is an important issue that affects a lot of people,” Maloney said. “Millions of hopeful, young Americans will find themselves between a rock and a hard place if Congress doesn’t act to prevent the doubling of Stafford Loan interest rates.” Student-loan debt is the largest category of consumer debt in the nation.
