well am in 12th standard as u know practical will going to start from Jan so all teachers are in bustle to check the practical nb and in that if any student make a minor mistake in that practical she just tear her page or just scrabble with her red pen in the nb and asked to write it again and she says that am not going to check let the examiner will check your nb I mean already all the students are in anxiety because of exams and we are not doing good in our pre boards and after this teachers are just like bad dream and sometimes I had a nightmares are also coming regarding this
