I like this idea:

About half of students who take the SAT do nothing to prepare. Grockit, an education start-up, wants to change that by making test prep social and taking it online.

On Monday, Grockit announced that it raised $7 million in venture capital, for a total of $24 million, from investors including GSV Capital and NewSchools Venture Fund, which invests philanthropic donations in education businesses and nonprofit organizations.

“A lot of problems in education are just related to the fact that people have to go to big buildings, live near schools or buy books or test prep classes,” said Roy Gilbert, Grockit’s chief executive. “The advantage of software to do this is, you remove the constraints of time and space and deliver it in places you’ve never been able to deliver test prep education before.”

The courses are social, so people can study with other people, chat with them while they are taking the classes, leave notes about their strategies for answering questions and share their achievements. Grockit’s founder, Farb Nivi, formerly taught Princeton Review teachers and discovered that students learn best when they teach one another, he said.

Kaplan should be worried.
