The best if you are a US citizen is with the government. It is not faulty, but don't expect to get paid. If you're a good student, and have been accepted at the college and major in pre med, you can get a scholarship. You get a scholarship you are going to have to do 10 weeks of research with the government. You can also work for them full time after graduation for a year. For more info:
