For many of the contests, it says that they will use "ICPC rules" or "extended ICPC rules." What does this mean?

ICPC (International Collegiate Programming Contest) is an annual programming contest for university students. The rule is that you'll have 5 hours to solve problems (about 10-16 problems), ranking is by solve count, penalty for breaking ties is by sum of minutes + 20 minutes per WA (only on problems that were ACed).
Extended ICPC rules is typically the rule that Educational rounds use, basically ICPC rules but with some changes. You get 2 hours for 6-7 problems, but the penalty is 10 minutes instead of 20, and WA on test 1 doesn't count towards penalty. But otherwise follow the same (more solves == better) + (penalty == sum of time) ruleset as in ICPC.
