How can I regain interest in my studies? TOMORROW are my exams?

first of all, will you please stop criticizing your skin color all the time..i dont really understand why ur parents keep on mentioning about your skin color..but on ur part first start thinking yourself as a very smart and stylish person..just feel positive about yourself..you are not the only one on this big earth with dark complexion..just think about so many hollywood personalities with dark complexion...and dont just think that every one notices your complexion all the time..no one really cares about other people's complexion..no one is having so much time to waste on bothering about other's complexions...when u feel confident inside, everything just goes well..so feel positive and confident...an for your exam tomorrow...well dont try to grasp everything in one day coz its just not correct..watever you are able to read, just understand it properly..and dont expect any miracle to happen..so studying is the only option ...good luck :)
