I messed up on my undergraduates. I transferred to university as a junior and didn't look for research right away. When I was trying to apply for a spot during the year, most of the research opportunities positions are full. I came from a science university so there is big competition among other students. It is frustrating as this will be my last year of undergrads and most professors request for sophomore and juniors. What should I do after I graduate for research experience?
