I will start university next year and I want to prepare for abstract algebra. I was recommended a book called "basic abstract algebra, by Jain, Nagpaul et al", but I don't know how good this is for a beginner. I have an online version of this book and am willing to send it to your email if you want.
Note: This question is very specific and hasn't been asked before, please don't close.
Thanks
Try "Contemporary Abstract Algebra by Joseph A. Gallian".
I personally love the text, (the questions even more) but keep one thing in mind, you won't understand the text until you solve most of the exercise problems. Well, that's how to learn to apply things, isn't it?
EDIT: I took a look over the book and it seems to be good. But I'd say you should stick with some "elementary" text first. Then move on to this book. The text isn't much different (maybe, when you've read a topic, all the books look almost the same), just the chapters reordered. In the book, the author goes from Groups to homomorphisms directly (and gives relatively less examples), though what I would want in a book would be proper "order?" Groups$\to$Abelian/Cyclic Groups$\to$Homomorphism(much later). I'd still go with the book I mentioned above.
