Private loans for 25k? Best option? Sallie Mae?

I’m starting a two year program that’s a 50k amount, my FAFSA will loan me about half but then I need to get a private loan for 25k still, what’s the best options? I have good credit. Sallie Mae ok? I just don’t want a 25k private loan turn to 50-70k over interest. Any help will mean a lot, none of my family ever went to college
