i m preparing for cat 2010.kindly suggest me good e- mathematical book of algebra………………

Hi Archana. I am not an American,so I am not familiar with CAT. Sorry, but no idea. Regarding Algebra books, my favorite is the one by University of Chicago School Mathematics Project. We have a series (very old edition) here in our library, but I am not sure if they have new editions. They have conceptual explanations. I am not sure though if the type of exercises there are similar with CAT.
