I feeled my rating and skill is stuck.
When I looked at my rating graph, I found it was just haning around about 2050 to 2150 average.
Every one says to be good, solve more problems, but I have solved almost every 2100~2400 (often 2500 and 2600) in div1,2 contests for last 1 year.
I think I am in some trouble. What can I do?
