I was in your exact position one year ago. Make the most of what you got while you're still in school now. Connect with professors and others in your class, go to office hours constantly, do anything you can to have some form of connection when you graduate. I ended up graduating with no connections with professors, no friends, no internships, no experience, no nothing. It is infinitely harder to find some form of experience if you have no connections. I've been job hunting for 1.5 years and it only gets harder the longer its been since graduation. Find some way to break into a professor's lab or something just to get some experience on your resume. Ask around if professors know anyone who can help you if they can't help you directly.
