Amid Reports Of IPO Plans, Chegg Acquires Lecture Note Marketplace Notehall

We’re hearing that online textbook rental service Chegg has completed its third acquisition today, snapping up lecture notes and study guides service Notehall for an undisclosed amount of cash and stock.

Chegg, which has received over $219 million in financing and hit revenues in the ballpark of $130 million in 2010, is also reportedly “deep in talks” with bankers regarding its plans to go public.

Notehall, which like a micro-Chegg congruously offers a platform for students who want to buy and sell course materials, will be Chegg’s third acquisition after it snapped up other education-related startups Courserank and Cramster last year.

Notehall was founded by University of Arizona students Sean Conway, Justin Miller, Fadi Chalfoun¬†and D.J. Stephan in 2008 while they were still at the university. The startup was originally financed with co-founder Justin Miller’s bar mitzvah money and eventually ended up taking part in the Dreamit Ventures incubator program as well making an appearance on the TV show Shark Tank.

Notehall currently offers its services at 54 universities across the US and pre-acquisition was expected to grow 400% this year, hoping to hit 750K users by the end of 2011.
