Hello Sir,
I am going to appear for JEE-Main 2015 next year. In my class 10
marksheet, there is a mistake in my father's name. Actually my father
doesn't write his title(last name) in the end, just the first and the
middle name but in the 10 marksheet, the last name is printed. Whereas
in my class 12 marksheet, there is no mistake.So i'm worried if i am
going to face any problem at the time of admission in an engineering
college next year ? What should i write in Father's name box in the
JEE-Main 2015 application form- the correct name(which is without last
name as printed in 12 marksheet) or the one as printed in class 10
marksheet ? Please help me in this regard. Thanks

Yeah you will face problem.Please follow these steps
