Prerequisites :
You need the experience of solving 2 problems in any online judge (like Sphere Online Judge (SPOJ), Lightoj, Codeforces) in any programming language of your choice. That will give you an idea about how are your programs tested online. After getting some idea about how online judge works, you can very well start with Topcoder.

Topcoders are divided based on their rating as Grey coders(Beginners), Green coders, Blue coders, Yellow coders and Red coders(PRO's). Coders are divided into two categories Division 1(where Red, Yellow and Blue coders compete) and Division 2(where Grey and Green coders compete). You can register for an SRM from 3 hours before the contest time to 5.01 minutes before the contest time. There are two phases in an SRM
1) coding phase 2) challenging phase. More explanation can be seen here.
Your base rating is 1200. Your rating changes according to your performance in SRMs.
You can get a complete idea of rating by looking at these graphs
