i forgot to write the question number in my english board exam for article and notice but i did write the section b writting skills on top and attended all question serial number wise .i am worried will those answers be accepted ?????and what are the consequences

Though going by the rules, marks are deducted for wrong numbering of the questions, the level of deduction would depends on the individual examiner. Take care that you do not repeat this mistake again; not only in your boards but in all exams that you are going to take in future. As of now, hope for the best. Good luck, Prachi!
