    no, you won't lose points for solving a problem.

    You get a minimum of 30% of the full number of points if you solve a problem, regardless of the time and the number of wrong submissions, if it is div2.

    Every problem has a minimum points for AC associated with them, so regardless of how many WA you do you will get those minimum points at least. For a problem worth 500 points, usually points allotted to Div2A.

If your submission is hacked during the contest or in 12 hour long hacking phase of a contest like in the case of a Div 3 or Edu Round then yes your rank will fall. If your submission fails system testing then also the rank will fall.

However, if the submission passes system testing and the system testing is 100% over and an individual manages to hack your submission after all this then your rating will not fall. For example check this submission, the guy got hacked after the contest but since passed all system testing his rating changes were unaffected.

    Well then, can you please offer to tell if my rating will fall? I am hacked after contest, but because there is an "invalid system test" in B, all of the submissions got retested, and that hack-data is included in the system test, resulting in an FST. I am a little bit disturbed and wondering if my rating will fall dramatically.
