Hi! I am using an alt acc so perhaps my rating is still low, but on my main account my rating is around 1600, and reading advice, I should do 1700-1900 rated problems. However, the thing is that I tend to spend around 2 hours to solve 1700 rated problems and I can't even think of 1800 rated problems sometimes, esp 1900 I just can't solve it at all. For 1800 rated I solved 14 and alr attempted 13 while for 1900 rated i solved 8 and attempted 3... Thing is somtimes the problem is so easy and other times I can't even think of the solution at all. Does anyone have advice on what should I do or should I learn what topic? Or should I just back down and lower problem rating I'm practicing with or just do 1800 rated now? Thank you, appreciate any feedback!
