Keep confidence and be focussed on your goal.मेहनत करने वालो की कभी हार नही होती so work hard until you reach your destinationSolve some good books clarify your concepts like dc pandey hc verma for physics ms chauhan n avasthi and vk jayaswal for chemistry sl loney for maths And practice as much as mcq in time limit you will definitely be able to crack it pleazzz approved me
