I don't understand how codeforce rating works
By HEVNTR, history, 3 months ago, In English

Heloo coders, happy Lunar New Year to everyone. I'm here today to ask about the scoring system on codeforce especially in the contest scores. Firstly, in div3 the score is usually like + +1 +2 +3 +4 +5,... I don't know how that works. (I do understand how pen works tho) Secondly, in div1 div2, although the submit is full AC, people have different scores from each other, some even have negative red scores. I would really appreciate it if anyone can explain this to me, happy new year again and have fun coding.:D

+1, +2, +3 means they failed 1, 2, 3 (got WA/TLE...) and + means they got AC in 1 submission

Div.1/Div.2 has scores depending on the time and number of failed attempts

Red scores means they got hacked or failed in System Tests (passed Pretests)

there's two type of rating rounds, one has +'s and other penalties, if there is a -x that means the person tried to solve x times but solution didnt passed all the tests, if +x then he had x wrong attempts and 1 correct, if there is a number that means the guy may had some wrong answer and got -50 points for that, so if he solves that problem he will get -50x points for x wrong attempts and also time penalty for every minute
