DSA for SE and LIFE

Can anyone help me with cracking PBCs, I work in a MNC, I am not able to study dsa ( I have my own mistakes too ) , but to move forward in life from 5 LPA and fulfill my responsibilities , for a common middle class software engineer, high paying job is the only way to take care of family and ladder up in life... I request anyone who can guide me and support in DSA and crack a PBC

Middle class SE ( Software Engineer) ✌️
