How much time does it take to develop good problem solving skills (from ur experience) ?

So I am 2026 aspirant and I started my prep from about mid november (ik i am late due to some reasons). the first thing i noticed about my prep was that i was facing a lot of difficulty in solving questions. it's really hard. it's not like i am dumb or stupid. i have good problem solving skills in math and science. i scored 95 in math in 10th (ik 10th is really easy as compared to 11th but i am just telling this to give an idea that i am fairly ok in studies like not really bad or something).. so my question to all seniors here was how much time did it take you all to get comfortable with solving problems after you started your prep ? I am taking a 3 months challenge at this point where i'd devote atleast 6 hours per day to solving questions. this would amount to 540 hours at the end of 3 months. can i expect to develop really good solving skills by the end of 3 months ?? or it would take more ? how much time did it take you and what was your experience ? plsss help mee
