Searching for some college books …

Are there any ‘sets’ or pages for college courses instead of searching one by one (I already tried searching with no luck also).
But basically I want to see if the books for engineering would be available. From the basics such as Algebra, I am finishing up my degree in eco/stats this year and seeing if I want to go for the masters or just study on my own. (in my situation I only need the knowledge, not the degree/title).
So just looking for basically whole college undergraduate degree plan in books.
Thanks in advance.
