Okay,

So, sorry if this has already been brought to people's attention, but I couldn't find this using the search function, and have lurked for awhile on these forums, but found this myself:

http://departments.central.edu/actsci/exams.asp

There are whole e-books that are free on this link. Is there any reason to believe that purchasing a text to aid in studying would be better than these texts offered?

Regards,

Steve
