    I think there are none. You can participate in every round without depending on results of the previous.

    All three main rounds are independent, the results of participation in each of it do not affect the possibility of participation in next rounds cit.

    for each problem, judge has 20-100+ test cases. when you submit a problem in a contest in codeforces the judge test your code by 2-10 test cases. If your code passed after judging by those test case then they will give you a verdict "pretest passed". After finished the contest judge will test your code by all the test cases. . for more details you can read this post: http://codeforces.com/blog/entry/456
