Is graduate school as rewarding as college?

Graduate school is very very different than undergrad. It's much more intense and focused on cl work/research. How much socializing goes on depends very much on the graduate program whereas any undergrad has a social scene. But it's way to early for you to be worrying about meeting a potential spouse and graduate school, focus on getting yourself set to apply for undergrad. You really don't know who you will be in 5.5 years when you apply to grad school.
