Central Board Of Secondary Education [CBSE] — Malpractice occured in term 1 and it also happened in our school

This is a student from chennai india. i am currently studying in grade 10 in sri chaintanya techno school
and as we all know the cbse council has released term 1 marks and I hope the members of cbse have heard malpractices occured in term 1 mainly in tamil nadu zone and its completely true and this incident also occurred in
our school and totally for 4 subjects we got answer key before writing the exam our school also don't have authorized license and the id card provided by our school registered under some other branch. they provided id cards before going to exam center. actually our exam center was st.john public school and it is located at Lake Bund Road, Off Perumbakkam Main Road, Chennai City, Tamil Nadu. when i went to exam hall everthing was alright but before 30 mins of exam the staffs of our school released answer key they told answer key for 20-25 questions for 4 exams and the staffs of our school also got soft copy of pdf before writing the exam every student are eagerly waiting to ge tanswers but as only few time left some students wrote answer key in hall tickets because and it is not even easy to memorise all the answers provided by our school and student of our school also copied in restroom and i heard that some students brought smartphones and they kept inside there panties and copied in restroom and the staffs of st jhon school is not so strict and they staffs in st jhons schools also helped some students by telling answer key . in maths we got 36 answer from our school and for english we got answers from question number 11-40, they other subject also and they told answers for the students who got very low marks in pre board but the our school principle did't even know that the school as done malpractice. the teachers who accompanied with us also told not to let out secret about malpractise and if your not trusting me you can check or investigate our school staffs or the staffs in st jhons school and for some subject they gave the question paper very late and delaying for more than 30 min so please enquiry our school about malpractise and please reduce the weightage of term1 and the letter i wrote should be effective because this the life of every students and the letter contains only truth and if you are not trusting me please send cbse flying squard to our school to know all malpractise occured in our school Thank You.
