I am an undergraduate physics student studying in UK. I hope I can continue study to PhD in the future, and I heard that I have to or better to apply a research internship in summer in order to go further study. But I have no idea how to apply and what I need to do in the internship. Since I am quite shy in school, I think none of my professor recognize me, so I am afraid I already miss the chance of internship. Also, what I should do/prepare now if I want to go further study in future? Please someone help me >.< I thought I can think about it later but it seem it already so late. :( Thanks a lottttt.
