Federal Loans

<p>When i take a federal loan am I charged ZERO interest on the amount??does this hold true even after the 7 months after I graduate from college?Also my EFC is zero and I’m still deciding between Gerogia Tech & UC San Diego.I’m living abroad rite now but will shift permanently to CA soon…so I’ll be in-state for the next 3 years at UCSD…If I go to GTech I end up with $8000 more in loans than UCSD.Is it worth it?(my major is mech engineering and GTech wins hands down in undergrad engr. rankings)</p>
