Actually they used it last year too, and it had problems then. They new tons of students would be uploading programs all at the same time, they should have known to stress test the grader beforehand. |

What was wrong with the grader last year? |

How about everybody's score by your school teacher initial grading ?
My score is 62 in Senior Division. ody
Anybody could expect what kind of score will be the cut off for CCC stage 2 ?
Thanks for everybody's input.

When are the test data released? Our school didn't get a grader (which looks like a good thing...). |

By the way, the online grader is extremely slow.
After each submission, we get feedback after 20-50 minutes. How about the response time at your school ?
Our contest began at 12:00 yesterday, this might be the peak hour. |

Peter My prediction (which is usually wrong) is that the cutoff this year will be around 63. |

Your teacher should have the test data. Ask him / her for it?
How can not using the grader be a good thing? |

It seemed like a big headache for a lot of people, and from the looks of it, it gave wrong answers sometimes too. |

The advantage of the grader is that you might be able ot get feedback during the contest while a teacher grading you only get marks after everything is done and basically get 1 submission. In general onlin graders aren't great, but I'm pretty confident that they work fine but they check output character by character so hidden spaces can ruin a program and cause it to be wrong even though it looks right.
If it is any reference, last year you needed a 64 to make round 2 but I haven't looked at this year's problems to see how they compare. But my guess is > 60 for sure if it is similar difficulty and 63 will be really tight.
The upside is that you wrote it. I believe that a bunch of schools couldn't write it this year with the teacher's strike |

The problem is that most of the people in my class, are idiots, no offence to them. So because they could not answer the questions they linked a random number generator to how many different answers there are and they submitted that program 50 times each, so imagine only 40 people in my class submitting 50 things to be graded per 4 questions. |

It took DWITE a couple of years to run into and refine all of those issues. We previously saw crazy things along the lines of students submitting a zip file of their Visual Basic project as a "java" solution which made the compiler crash in very bad ways. |

They've started to regrade all solutions on the online grader. |

Will it be regraded with a 1 minute time limit? |
