I feel like today is Virtual World Day. We started off the morning covering the public beta launch of Vivaty, then Second Life and IBM announced that they bridged two virtual worlds, and Google launched its own version of virtual worlds with Lively.

If it seems like everybody is starting their own virtual world, it is because they are. A report put out today by Virtual Worlds Management tracks $161 million put into 14 virtual-world investments during the second quarter of 2008. In the first quarter there was even more activity, with $184 million put into 23 virtual worlds and supporting technology companies. That brings the total this year alone to $345 million across 37 deals. Some notable deals (you can see the full lists by clicking on the last two links above):

We don’t know much about Grockit. The company is creating a new way to get people to learn online, and has spent the last year working away in stealth mode. Whatever it is, it’s apparently impressing investors: Grockit just raised $8 million in Series B funding from Integral Capital and Benchmark Capital, bringing its total to $10.7 million – impressive for a product that has yet to see the light of day.

According to the company’s press release, Grockit is “a MMOLG (Massively Multi Player Online Learning Game) where people can connect to learn from each other”. The company hopes to release the product this fall.

Grockit originally launched in November 2006 as an online exam-prep class that competed with companies like Kaplan and The Princeton Review. In July 2007 Grockit announced that it had scrapped that idea in favor of their current plan, and raised a $2.7 million Series A round led by Benchmark and angel investors.

The company was founded by Farbood Nivi, who taught in the exam-prep business for years, and Michael Buffington, an experienced Rails developer.

Anyone who’s applied to college has dealt with the frustration of standardize testing. With the cost of failure so high, parents and grads continue to spend a lot of cash on test preparation to ensure the best results. However, there’s a crop of web startups popping up to ease the pain and we’re all benefiting from the competition.

Prepme is one online test prep company coming out of the University of Chicago’s business incubator. Founded in 2001, the company offers test preparation for the SAT, PSAT, and ACT, using an adaptive algorithm to customize the preparation course for each student.

Unlike Kaplan’s online offering, Prepme doesn’t calculate the best lesson plan once, but continuously as you work your way through the material. Their system keeps track of what questions you get right and wrong, working you harder on the types of questions you miss.

Additionally, customers can connect electronically, using real time chat, with high scoring college students who serve as tutors.

With test prep for the SAT alone being a $130 million dollar-a-year industry, using web 2.0 technology to help students seems like a logical move. Seeing the threat, some of the major players in the industry, like Kaplan or Princeton Review, have been attempting to develop online test prep products to compete with new online offering like Prepme. Prepme charges around $300 to $500 for their lessons compared with Kaplan’s lowest offering costing $400.

At the same time, Prepme is expanding the tests which they provide preparation for to include the GMAT, MCAT, and LSAT and partnering with brick and mortar companies to provide comprehensive test-preparation services. Additionally, the company signed a contract earlier this year to provide their services to every high school junior in the state of Maine.

When we last wrote about San Francisco based Grockit, in late 2006, they were unfunded. Their business idea of holding low-cost GMAT prep courses over Webex was just getting off the ground.

Now they are funded – $2.7 million total ($2.3 million from Benchmark, $400k from angel investors Mark Pincus, Rob Lord, Reid Hoffman Thomas Ryan and others) in a Series A round was closed last month. And they are changing their model completely.

Instead of holding one-to-many classes via Webex, the company is building a new product from the ground up. Founder Farbood Nivi calls it MMOL, for Massive Multiplayer Online Learning (a play on the term MMOG). He says studies show that people learn best from eachother, not in a teacher-students situation. He, along with technical co-founder Michael Buffington (Price.com, MeasureMap, Stikkit), are going to try to prove this works. Beyond that, they aren’t divulging any details at all.

Entrance exam preparation is costly and not exactly what I’d call fun. A company that launched on Monday called Grockit is dropping costs and making the process a bit easier to get through.

Grockit was started by Farbood Nivi, who has been teaching exam preparation since 1998. He worked for Kaplan and was Teacher of the Year for The Princeton Review in 2002. Just a few months ago he decided to start his own prep school where students can attend WebEX classes.

Grockit is significantly cheaper than the major review schools but Nivi says his profit margin is bigger.

“The other guys tend to be enormously bloated as far as companies go,” Nivi said via IM on Thursday. “They have very inefficient operations. They spend $1.5 million to generate $1.4 million. The virtual world is cheaper and more pervasive.”

To start out, Grockit is offering 16 90-minute sessions plus the official GMAT review text books for $399. Kaplan online is $1,249, The Princeton Review is $899, and Manhattan GMAT Prep is $990. Nivi says that the Grockit price may go up a little within the next year but he doesn’t have actual plans to increase it.

“One student has dropped the course with a competitor and decided to buy a laptop with the money he is saving by taking Grockit instead,” Nivi said. “Taking one of the big guys means that just applying to a hand full of MBA programs is a couple of thousand dollars out of your pocket.”

For now, Nivi is satisfied using WebEX where students and teachers can chat and interact. In the future he hopes to develop his own software for interactive classes. He also hopes to branch out from solely GMAT prep and start ACT courses next year because he believes that the ACT “is going to eat the SAT.”

To promote his service, Nivi and his staff of teachers have signed up as experts on BitWine. They are also banking on word-of-mouth marketing, hoping that saving money is a major incentive for hopeful students.

The obvious question here is if Grockit is a get-what-you-paid-for type deal. Having not taken entrance exams in six years, I couldn’t think of appropriate questions to quiz Nivi with but his experience is impressive enough to say his school is worth serious consideration. Especially for anyone considering dropping major ducats on an MBA.
