For all those who have done bad in their prelims physics paper 
just think that u are a big match player , your performance is dependent on the occasion 
all the previous exam were just a small battle but if u win this last battte of physics tommorow  u win the war
remember that the numbers which u get on the paper will have no value in your life  its  the journey which u traveled to get that numbers which will built your personality and direct  your life 
give all that u got .NO GUTS NO GLORY .
LETS NUDE THE PHYSICS PAPER COMPLETELY TOMORROW
