Hello student!

As per your query I would like to inform you that it if your mother's name is different in your class X and XII board marksheet and that in B.Tech degree, it should not create any problem in taking admission for higher education abroad. But, for a safer side you can prepare an affidavit which should have both the names of your mother mentioned in class X and other in B.Tech degree which declares both the persons are same.

Hope it helps!!!
