Does it ?

This 22nd of october, We are witnessing something entirely different. 3 contests Div1, Div2, Div3 running parallely.

Even though there are 3 days left for registering, there is quite a chance the Div 2 contest will be given entirely by experts.

I was wondering if this makes it more difficult for positive delta or nothing changes ?

Hello Codeforces Community,

I have recently turned expert in the previous educational round. And now seek advice on how to conquer the next step — Turning Purple

I have solved lots of questions in the 1400 to 1500 range which helped me in consistently solving A B and C in almost every Div 2 contest. Whenever i attempt a 1700 — 1800 problem it seems way too difficult from what i have previously solved.

Are there some advanced algorithms or concepts i need to learn before practicing to conquer the next step ? Or spamming practice is the answer ?
