<human>: Give me the gist of the text in a nutshell

Sorry if this is not the appropriate subreddit to post this. 

I currently just finished this semester at a community college. I took 4 classes(Bio 1406, Speech 1315, Art Appreciation, and Philosophy 1301). I got my grades on Monday. I received an A in Art App., B in Bio 1406, C in Speech, and lastly an F in philosophy. Bringing down my gpa to 3.16. 

I was eligible for FAFSA grant and received money from them which I used to pay for the class. Someone told me that if you fail a class you have to pay back FAFSA grant. But someone else told me that if your GPA is above 3.0 your okay. 

I can provide more info if needed. 

Now my question is:
Do I need to pay back all my financial aid? 
Do I need to payback the cost for this semester? 
Do I payback the cost for the one class I failed? 
Will I actually have to payback the financial aid or will they let it slide this time?
<bot>: Failed 1 out of 4 classes this past semester. Used money from financial aid to pay for it. Have a 3.1 GPA now. Refer above for the questions I have.
