Can someone look at my profile and suggest based on that what should I do to improve ? I am Usually able to solve question A and B of div2 without any problems but question C is where I get stuck. thus i tried to solve problems of rating-1400. I have solved about 35 (1400) problems 26(1300) and 29(1200),and I am still not able to solve C of div-2. I usually practice 2 questions a day of usually 1400 rating, My aim is to reach specialist untill the end of this year. Any sort of tips will be appreciated.

Background-I am a(starting monday) 3rd year college student ,so any tips on how to manage competitive coding with development as well as college studies will be helpful as well.
