Well, I can't say anything about your social media addiction find a solution to that but i can give you some tips for the exam So it's all about being smart about the exam i.e 1- Study Civics and Biology with a very high attention (trick: you study Civic and Biology and you know em in & out you won't miss a question in the exam as there is no probabilities rekated with theoretical concepts so chance of answering is >95%) (Focus: focus on the textbooks for both of em, they aint taking out the questions from Extreme in those subjects case😁) 2- Go for Chemistry on a second level (trick: Half of the questions are gonna be theoretical so aim not to miss any from em and study calculation based concepts with a probability) 3- Go for Maths here and the secret is practice (trick: solve as many questions as you can on each chapter till you feel confident enough to solve any question on it) 4- Go for Physics (trick: aim not to miss theoreticals and give probabilities for calculations) The strategy is: Waste a lot of time on Civics, Biology, Chemistry and English with aptitude as the chance of answering questions from these subjects will increase the more you study em since they are theoretical,  instead of wasting a lot of time on Physics and Maths & dump the rest to be better. so you if get morethan 85 on Civics, Biology, Chemistry, English and Aptitude + more than 75 on Math because you practiced as hell ....you are among the high scorers.
