How is the checking scheme of 10 class in board exams? I had studied hard for my pre-board exams, but still the marks I scored were less. Checking of my school teachers was very strict. Is it the same in the board exams?

Checking in pre boards is more strict than checking in Boards exam. This is done by teachers to ensure that a child is not becoming over confident by scoring high in pre boards and then not studying for boards. If strict checking is done in pre boards then the student will study harder for boards hence score good mark
