Hey PH community my name is Sieva and I'm the founder at StudySoup. We're building a Crowdsourced learning community for college students online. Top students can post high quality study guides today to help their classmates succeed...oh and they make money too!
I'm a huge fan of StudySoup. I personally know college students who are using their study guides and are seeing fantastic results. They've got a passionate driven team that is using real life experiences to help college students around the world ace study better and improve their grades.
