University of Iowa student Angie Platt, 20, is seen on campus in Iowa City, Iowa, Monday, July 1, 2013 . College students taking out new loans for the fall term will see interest rates twice what they were in the spring - unless Congress fulfills its pledge to restore lower rates when it returns after the July 4 holiday. Platt said the increase in interest rates for subsidized Stafford loans will add to her debt load, which is expected to top $60,000 by the time she graduates. AP Photo/Ryan J.

It's just another thing to add on. It doesn't help me; that's for sure," the Lakeville, Minn., native added. Efforts to keep interest rates from doubling on new Stafford loans fell apart last week amid partisan wrangling in the Senate. Democratic senators and the White House both predicted that a deal would be reached in Congress to bring the rates down again before students return to campus. But if an agreement remains elusive, students could find themselves saddled with higher interest rates this year than last. "It's kind of surprising; that's a big jump," said Rebecca Ehlers, an Iowa State University senior majoring in math. A $1,000 subsidized Stafford loan is part of her financial aid package and she said she's reconsidering how she pays for school. "I may work more or ask my parents for money rather than going through all that," said Ehlers, 21. She - and millions of others who use federal student loans to pay for their education - has some time before she has to make that decision. But not much. But that is little consolation for students looking at unexpected costs waiting for them on graduation day if Congress doesn't take action before it breaks again for the month of August. "I'm upset by it," said Kolton Gustafson, a George Washington University political science major heading into his senior year. I wish there was a larger reaction to it. "Many students are saying and thinking, 'I'll pay it later,'" the Grand Junction, Colo., native added. That's why you don't see more people fighting back. Students only borrow money for one school year at a time. Subsidized Stafford loans taken before Monday are not affected by the rate hike, nor are federal PLUS, Perkins or unsubsidized Stafford loans slated for the coming year. "We're telling members to advise students that interest rates are going up," said Justin Draeger, president of the National Association of Student Financial Aid Administrators. Subsidized Stafford loans go to needier students and often are coupled with other types of lending. He said he doesn't anticipate that the rate increase will prevent students from attending classes in the fall. The effects, he said, won't be felt until after students graduate, when they have to start paying back the loans. This doesn't decrease the dollars available to pay for college. It increases the cost of the loan," he said. During last year's presidential race, both parties pledged to extend the 3.4 percent interest rates for another year to avoid angering young voters. At the White House, a spokesman predicted a deal could be reached before students return to campus. "We are confident they will get there and that the solution will include retroactive protection for students who borrow after July 1 so that their student loan rates don't double," Matt Lehrich said. Back on the University of Iowa campus in Iowa City - where Obama campaigned against a rate hike last year - senior Julia Vander Wilt seemed resigned to the higher costs for her subsidized Stafford loans. "It's a little bit insane that we're paying so much," the 22-year-old student said. But I don't know if there's really anything I can do about it. Associated Press writers Ryan J.
