Before you pay for an objection
Work out your likely score first: 1 mark for each right answer, minus one third for each wrong one, nothing for blanks. Only challenge a key you can back with a reason, since the 50 rupee fee comes back only when RRB accepts the objection. Your marks after normalisation will come with the result.
