In the Science Magazine article The Critical Importance of Retrieval for Learning professors Jeffrey D. Karpicke and Henry L. Roediger, III describe their research into studying, learning, and quizzing (which they call retrieval practice). From the abstract to their paper, the scientists write, "The results demonstrate the critical role of retrieval practice in consolidating learning".

We have known for years that testing yourself before a "real" test will improve your performance. This is analogous to soccer practice or band practice. No one would just play soccer or a musical instrument without practicing, so why treat written exams differently? With Quizor® you no longer have to. Retrieval practice, or quiz taking, is the basis of the Quizor paradigm -- now validated by scientific research.

We know Quizor will give you the confidence you need to get better grades. Try it for yourself. You have nothing to lose because Quizor is now free.
