Great Amount Of hardwork is required if you are going to take this decision , NUMEROUS Difficult problems and sums have to be learnt BE HAPPY IF YOU ARE GOOD AT MATHS , PHYSICS, CHEMISTRY AND BE READY TO LEARN IN DEEP , and it is really going to be a long way ahead .
TAKE THE RIGHT DECISION
ALL THE BEST
GET ALL YOUR DOUBTS CLARIFIED WITH YOUR TEACHERS , AND OTHER EXPERTS BEFORE YOU TAKE THE DECISION
I MYSELF SCORED GOOD MARKS IN 10 AND 12 AND ALSO WENT TO COACHING CLASSES BUT AT THE LAST I COULDN'T GET INTO NIT'S AND IIT . AND IT HAPPENS IN MANY CASES .
SO CHOOSE THE RIGHT DECISION DEAR BROTHER

Yes but you have to take coaching for jee mains and you have to worked hard
