hello: i am considering going back to school to get a degree in business. i have borrowed a book from a friend who is already in the program. meanwhile: i sometimes have trouble working my way through the chapter questions. he said that they were not given all of those problems for homework, but i think that it is important for me to at least know how to work my way through most of them. is this a web-site that could possible help me with some of those questions or should i be seeking help from somewhere else?
