Good day to you all.

My younger sister wrote this year may/June 2017 WAEC result that has just been released.
The main issue or problem now is that when writing her examination she did not re-shade her examination number and sex in her objective answer sheet because she said that it has already been shaded by waec and that the investigators who supervised the examinations didn't inform the student to re-shade it. The big question now is that, is it compulsory for a candidate to re-shade the registration number and sex in waec examination objective to re-shade it again. Although this is her first senior WAEC examination.
My big worry is that will her results be released by WAEC or will it be seized as missing script?
.
Please i need your answer.
Thanks alot
