Good Morning...

I am a freshman in college going into my second semestar in September of 2008. I am in a 24 hour + major program. I left high school in 9th grade however, scored high enough to be placed in Basic College Algebra. I attempted to complete this course during this present semestar but struggeled so much that my advisor suggested I withdraw, continue an independent self study starting now until September in Introductary Algebra/Pre Algebra. I am confident in my abilities to study alone and learn the needed materials. I take all my classes via internet anyways.
The book I have is Introductory Algebra by K.Elayn Martin ***. I attempted to find the companion website for this text but wasn't able to locate it.

My questions are - are there any FREE resources online that can help me with my studies with this? Thanks in advance for any replies.
