Hi everyone, this is my first post and so I just want to say thank you in advance for any responses to my question. I recently applied for an internship which will take place over the summer of 2014 and it looks like I have a good chance at actually being accepted for the program. However, I have my academic career planned out for the next year and half. Within my academic plan I was prepared to take Mulitvariable Calculus over the summer. However, it looks like my internship might conflict with this course, but I still have the opportunity to take Differential equations. I have been told by other students within my program that multivariable calc would be ok to take over the summer but that it would be in my best interest to wait for diff eq until the fall because it is a more "important/integral" math class for physics majors. Do any of you find this to be true? I am assuming that they are taking into account that summer sessions are shorter and so there are certain topics which are left out so that only the most important concepts are covered. If this holds to be true then maybe I will just wait, I was hoping to get some insight from those of you who have already completed the math sequence.
