My school is offering me a job in the summer. They said I will get 3000 dollars at the end of July. Not sure if I should trust.
Challenge Considered
WHAT ARE YOU, INSANE?
Thats great pay.
Just think about it. 
Work monday through friday.
9-5 is a 7 hour work day (with lunch break)
June-July = ~40 days
Assuming $10/hour you will make:
 ~$350/week
 ~$1400/month
 so
  ~$2800 for June to July. 
That's alot of assuming, but thats more money than I make, and more hours. 
If you don't do it, I will.
