Kendriya Vidyalaya Sangathan — no online classes for my ward studying in masjid maoth kv school

My son was in xi commerce stream of kv, masjid moth. He has been declared to have retest in maths only. Id have been provided by ro kv sangathan to only pass students of xi. My ward is not provided any id. He was earlier attending xii classes. All of a sudden he was not able to login and school informed only pass students can attend online classes. I am paying fees for the acedemic session but no classes are provided to my child because he has retest which is not going to be conducted. I am not aware that in which class my ward is presently been considered because he is not allowed to even attend class xi online classes. This is injustics and is psychologically affecting my child. I may please provided clear cut information that wheter my child can attend class xii online classes and id be provided or he can attend class xi classes for which again id be provided. This may please be considered on urgent basis because time has already been wasted in case of future of my child.
