I need some advice... I have the option to take Linear Algebra from an excellent professor, but the course isn't required for my physics major and would only count as an elective for my math minor. Alternatively, I could take Calculus III from a mediocre (at best) lecturer. This course is required for both my physics major and math minor. I'm tempted to take the Calculus class if for no other reason than that Calculus II is still moderately fresh in my mind, but in the spring semester it will be less so. On the other hand, I have heard horror stories about the instructor and so am hesitant to take his course. Your input is much appreciated.
