Sneak peek: 'Big Brother 11'

From a neuroscientist to a surfing model, check out the new season's housemates

For the 11th season of "Big Brother," CBS thought it would be really fun to make these 12 strangers feel like they were back in high school. The cast members will be grouped into four stereotypical high school cliques—the popular, the athletes, the brainiacs and the off-beats. Also, a surprise additional housemate will be revealed to mix things up.

Check out the new members of the "Big Brother" house so you can decide which ones will be too cool, and which will just get schooled.

"Big Brother" premieres Thursday, July 9, at 8 p.m. ET/PT on CBS.
