Question regarding FIRE Streams

Hey guys,

I'm an incoming freshman in the freshman connection program and I was accepted into FIRE. The program seems pretty cool, and there's a specific stream that I'm interested in. What's the process for picking streams? Is it first come first serve? Is it when you sign up for courses for the second semester, and if so, am I at a disadvantage because I am in freshman connection? Basically is there anything I need to know/do to get the stream of my choice.

Thanks
