my twin brother and i were in the same kindergarten class (public school) but were separated all through elemetary and middle school but were back together in high school. i don't think it changed my education at all. we did have a tendency to fight over homework. (i heard the assignment one way, he heard it another and we'd argue over the right way to do something.) but in class, it really wasn't a detriment or an asset.

we did have teachers that tried to compare us to each other or ask why we didn't get the same grades on assignments or tests. we had different learning styles and abilities. yeah, we were twins but we weren't the same person. that was very frustrating.
