From http://www.alistapart.com/articles/designcancripple However compelling the message, however great the copy, however strong the sales argument… the way a page is designed will have a dramatic impact on conversion rates, for better or for worse. Here are three versions of the same o ff er pageI know, they won’t win any design awards. They weren’t intended to. But they are functional and familiar. A reader going to any one of these pages will be able to quickly figure out what the message is, and what they are being asked to do. Version A is the original.

What students are saying

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
