With this practice set I believe the system is a very ignorant one. I say this from a students perspective. I will give you this advice hoping that you will make this website better for students like me. When you get a problem wrong it sets back your score exponentially. I understand why you do this but I do not understand why you after we made one mistake not only dock us points but make each question answered correctly worth less points now. This system is quite frustrating and if I was just and individual using your site under no pressure or obligation from a teacher or a peer. I woud not use it because it is so frustrating. I hope this helps you understand my and many of my peers problem with this system. Thanks
