Spring Course Request Already!?!

I'm getting quite nervous in the service because starting next Tuesday there will be a mad dash to apply for spring courses. Being an engineer, I have my schedule mostly planned out for my next semester, yet, I am eligible to drop out of both Physics 2305 and 2306 and I will also need to start my sophomore level mathematics. I am meeting with my advisor for the first time next Monday to hopefully clear all my questions and my worries up. I also plan to pay more attention to course time slots so as not to give myself five classes on Monday in the future.
