1GUYS,A SINCERE ADVICE FROM THE CORE OF MY HEART,I BEING
A STUDENT OF CIV,FROM NIT ALLABAD,FIND THE PRESENT SCENARIO FOR ENGINEERS VERY GRIM,TOO MUCH COMPETITION,SAME HARD WORK IF YOU PUT IN MEDICAL ENTRANCE YOU WILL SURELY CRACK IT,NOT MUCH INTELLIGENCE IS REQUIRED.
YOU WILL LEAD A HAPPIER LIFE BASED ON YOUR OWN TERMS,YOU WILL HAVE NO BOSS,YOU WILL BE YOUR OWN BOSS,EARNING MORE THAN ANY IITIAN,NO RETIREMENT.UNLESS YOU ARE SURE TO CRACK IIT WITHIN TOP 3500,GO FOR IT .
OTHERWISE YOU WILL ONLY DESTROY YOURSELF.THINK WISELY .A LATE DECISION IS BETTER THAN A WRONG DECISION.
