I'm taking a first course in linear algebra, and my textbook very bad and the professor cannot teach. I need another textbook to help me self-study for this course that I am taking right now. I looked around Amazon and found that Linear Algebra: A Modern Introduction, by David Poole has good reviews, but they all seem biased. Has anyone used this textbook? Would you recommend it? Please recommend me some textbooks and study guide that are easy to self-study from.
