hello everyone and sorry for my English in advanc. I just want to inquire about something. why in educational rounds and div3 rounds there are no points for problems I think this is unfair, especially since it has become rated for div2 , It makes no sense that someone solved a and b problems to be ranked above others who solved c problem and higher because they got a mistake in one of their (a,b) problems after the contest is over , Please explain to me why the system of such rounds are like that and why they couldn't put points for the problems. thanks for reading :)
just take it the positive way...learn to code accurately since you know that the type of contest is costly if you miss the easier problems. Good luck and never give up!!
thank u for the advice of course I will never give up, Good luck for u too.
