Central Board Of Secondary Education [CBSE] — Complaint regarding the incomplete course in schools and conducting exams

Respected Sir/Mam
This is to inform you that I'm a student of class 11 of Modern Public School Shalimar Bagh Delhi-110088 which follows all the criteria given by the The Central Board of Secondary Education (Cbse)
Sir/Mam, This session[protected] our examination course was not yet over (not completed on time) and our school announced the datesheet for the final exams which will be held from next Monday (21st Feb 22) and we have our practical exams starting from Wednesday (16th Feb 2022). Sir our school is conducting offline practicals and subjective exams for which we are not prepared and haven’t got practice even once after the pandemic and this is our first time for the practicals in 11th class. Further more our course is not yet complete for the practical exams and for the theory exam it was forcefully completed. As well as we are not very familiar with all the chemicals and experiments in the chemistry labs. To be prepared we need time but school didn’t provided us with time for the same and they are conducting exams. (All the practicals were rushed and conducted in a very limited time only 2 days due to which we are lagging in some of the practicals)
Further our school kept a holiday on Monday (14 Feb) and we only have the last day left i.e. Tuesday (15 feb) as from Wednesday we have our practical exams.
Sir we haven’t talked to the school authorities yet because they will say we have done everything online, we've completed the course from the side of school and its your headache how to complete the course. In addition to this our school demonstrated all the practical online to us and says us that course is complete and give offline exams. This is not fair because if we dont have the hands on the laboratory items we cannot perform the practicals.
Sir, I request you to take necessary actions against the criteria of our school for the exams
Thanking You
Your Obediently
Student of Modern Public School
Class:- 11
