which would be better?(money talk)

So with my paycheck coming tomorrow I'll have about 2 grand to spend. Would it be better to make double payments on my bills which would leave me with about 500$ left. Or should I just make my monthly payments and keep saving? I'll be having to quit my job in about 3 months due to the school I want to go to will be full time so I'll only have my other side job to go off of. So money will be tight. Don't know if it'd be better to get some payments knocked out or just keep saving it for when I quit my job?
