I have been doing CP for past 2 years but my rating is not improving.I parcipated in my many contests but i could not even solve div2 A problem many times...At the time of contest, logic does not click to me and when i see the solution it seems so easy..then i think why i could not solve the question..I read some blogs to get rid of this problem is to solve questions 100 rating above your current rating but i did not work for me.Can anyone suggest me the right path to practice.
