Hi ! to whoever is reading this . I know this is another post crying out for some help to reach Pupil or Grandmaster but please , I really need some guidance . I had been practising CP from last 1.5 years on various platforms ( CP , not DSA or core concepts ) and initially I could solve Div 2A , 2B in half and hour and 2C after the Contest :( but I was never admant to reach an appreciable level on the platform.
But , SInce last 20-30 days , I have been toiling hard and practising and studying DSA and all the core concepts of CP on various platforms , solving problems , reading solutions and again repeating the cycle and this time , after a very large gap , I decided to again take the challenge and reach atleast reach green in 2-3 Contests ( too much overconfidence ) but , to my shock , I rarely cross Div 2A these days and Div 2B also seems undoable . I don't know what went wrong in that large gap .
SO , this is just a request if some experienced people can guide me — has the margin of Codeforces Problems risen up ? And even if they did , where am I lacking , do I need to solve more DSA and do contests regularly or be more focused on problems (since the DSA problems I did were of Easy to Hard but with proper problem tags and highlighted the concepts to use or I need to solely focus on Problemset of CF ? Please , this a gentle request from my side , I would be really grateful .
