How can I use my extra time while job hunting. need advice

I have been job hunting for more than a month now , but no response since I am a new graduate. so in the meantime I have plenty of extra time and I want to use it in a productive way. is there anything such as taking some short training or classes to enhance my knowledge in the medical field and at the same time it can be a bonus in my resume? I dont have any idea beside the CPR training at the Red Cross. I would deeply appreciate if anyone can share their oppinion,ideas or give me some advice. Thanks you all. I live in New York City.
