Hi, I was wondering about your opinions and recommendations on some physics texts, both free and costly. In about a half a year I'm going off to college, but I'm not sure if I'm ready for college yet. By that I mean I'm not prepared to make all A's, which I'm aiming for. But of course, my asking this isn't solely on grades themselves, but I want to actually start "learning" which I haven't been doing much of my years in high school because I absolutely hated learning stuff. But now, in my senior year, I feel as if learning is the best thing anyone can do. So I'm looking for a good introductory physics textbook based on calculus, and I would appreciate your help! Thanks.
