I have decided to use CSES introductory problems understand every concept presented in them and then move onto codeforces 800 rated problems as the easiest are doable but the upper echelon of 800 rated problems are still difficult to figure on my own It has been 2 weeks since I have started competitive programming after tackling 800 I'm thinking to start CPH is the approach right? any guidance or correction in my approach would be highly appreciated.

Thanks for taking time to read this
