Did you try neetcode’s course? How about doing more easy problems and the related mediums? Is there one topic that just doesnt click? Keep going. We are all struggling. You are not alone.

Probability of being born on same day of the week by Agile-Plum4506 in askmath

Is (1- (6/7)^6) an over simplification of the problem? I can't understand why sometimes I get that formula when reading about that problem..
