Help , thinking about dropping math before deadline. Is Math 1M03 being offered in spring/summer term 2012? How do I register if it is? Thanks

I am not sure if it's offered (maybe talk to you professor and see if it is, he/she MIGHT know). You register for courses on mugsi when the spring/summer course selection opens up in march.
Actually it's better to talk to your counsellor, they tend to know these things and will give you a solid advise.
good luck
