Hello, I'm a math major so this is primarily posed at people who have done math REUs, but I welcome comments from the physics people as well. My question is: How does taking part REU compare to just doing research on your own under minimal supervision by a professor? Are REU's just more structured? More group oriented? If you have done both do you prefer one over the other? I ask this because all the decisions from the summer programs I've applied to are starting to come back, and I'm trying to decide which genre of program to partake in before I chose a specific program. Thanks for your thoughts.
