Here's the issue: I am a junior chemistry major and the time has come for me to take a physics class called "Physics for Scientists". I have never taken a physics class before and I hear from my peers that not only is this particular subject extremely difficult, but so is the ONLY PROFESSOR teaching it. I won't go into too much detail about that, but I'll just say this. His class average is a 45%. So naturally, I am extremely worried and would like to get a head start before the new semester rolls around in a few months. I tend to catch onto things rather quickly so I'm not really looking for a beginner's textbook per se.
