Need Help Deciding on a student loan

I need to pay about $4,000 tuition for next semester.
even though I make about $2,400 a month, i have expenses and personal loans to pay to people monthly.

so i was trying to figure out a way to pay maybe $200 per month for my tuition instead in a 2 year period.

i am in my junior year of college and have about 1 semester left after my next semester.



Companies i have been looking into.
Wellfargo [wellsfargo.com]
Trufit
[citizensbank.com]
Discover [discover.com]
Chase [chasestudentloans.com]

If you guys have any experience with these companies, any thoughts on fixed vs variable interest rate, it would be greatly appreciated.
if you know any hidden fees or such please let me know.

i notice only trufit student loan said there is no prepayment penalty while all the other ones doesn't mention it at all.
Also most of them mention no in school payment required but i would rather pay it off early instead.
as with chase, they are showing no rates at all, if anyone knows te rates let me know thank you.
