Central Board Of Secondary Education [CBSE] — injustice to students of set 3 (cbse maths 2019 board exams)

Respected sir/ma'am
I'm a student of class 10 from uttar pradesh and on 7th march 2019, board exams of class 10th maths were held and three sets were given by the teachers. My set was the third set and i compared my set with my friend's set then very few questions were matching with the other two sets and i felt discrimination rising in my heart.
As soon as i left my centre, i heard many other voices being raised against this new set system. One question in my set was neither in two of the other set such as volume question and converse of pythagoras theorem. I've have many questions regarding this that is it my unfortune that on the very first day of my boards, i got the most difficult set and when i called my friends for the same issue, they said that they were lucky and they didn't even studied the things that came in my set. Should not students be judged justly?
We have been taught that indian constitution prohibits inequality and gives equal opportunity to all, then why should the students with difficult set should suffer? It's not the proper criteria to judge students like this, i'm not the only one raising voice against it. I'm only the part of huge number of voices raised by the people from different states around the country.
One student says that he/she is lucky and on the other hand, other says he/she is unlucky. This is not examinations. Then it should be like this that we should sit in temple and pray to give easier sets?
Sorry to say but it's my first boards and i'm also totally against grace marking because giving students marks with then deserving is the most unfair and corrupted practice in examinations.
From ancient times in india, examinations are termed as sacred and i believe cbse as a holy organisation spreading education but now i'm really disappointed in cbse due to this chaos. As a student, it feels awkward to see different questions in examinations especially boards.
I hope my request (Not complaint) will be heard because in india, we are taught to raise voices against any unfair practices.
