Say I'm studying circles or permutations nd combination or projectile motion {olympiads} and I've understood+memorized the theory, formulas...my teachers tell me to solve a torrent of questions by looking/not looking the solution and then I would be able to solve any new or old questions...what exactly is happening here...it's not memory since you will be asked a completely new question on the day of the exam and even if the similar question is repeated you haven't really memorized the questions solutions you've only gone through them introspectively or solved some questions on ur own...then what is happening here...what EXACTLY is the biology/science behind this phenomenon of mastering the art of problem solving??

Good series but the white backdrop can be quite taxing in the eyes, certainly when watching with tv, any chance of black backdrop
