r/CBSE

I failed in 11th(CBSE) on all three subjects PCM then I gave re-exam and only passed in Physics....then Moves to my hometown Bihar here i thought that I will take admission in 12th(NIOS) but I changed my mind after I found it it's complex then I go to a Bihar board school they said I have to take admission in 11th they can't take direct admission for 12th then I go to another school which is CBSE they said we can take the admission after submitting all the documents and after a month they said CBSE rejected it cuz I am failed and it's already August.....is there any options rather then starting form 11th again or NIOS

For context , our school had a new maths teacher for 11th grade , he is also the class teacher of 10 C , The guy literally finished trignometry in 2 days [Yea , he doesn't teaches any good , most of the PCM students agree] , recently he started taking out his anger issues on the students and basically targetting them as students complained about him to the principal , so the students as expected retaliated by nick naming him "BAJJO" , just studying by themselves in his period [solving modules , doing written work etc] , cracking jokes+hooting when he targetted a student , not taking him seriously at all and when he asks for pen , chalk or any minor help , students totally ignore him. This went on for 20 days and yesterday he cried , LEGIT CRIED , because no one was solving the question on the board rather students were doing self-study or written work and whenever he entered the class or left it he heard the word "bajjo"
He refused to enter the class anymore crying and said he was having sleepless nights + depression due to the bullying by the students and he loves his profession + wishes to teach extra stuff but this bullying is giving him insomia (his legit words) , I kinda felt bad for him 🥀 but his a-hole behaviour is the one which triggered such reaction , nevertheless all classes were suspend yesterday and seating arrangement was changed , and out principal gave 1 hr lecture on how the students are bullying poor maths sir and how skilled he is.
Today he was calmer and had a talk with the students (and indirectly apologised? he said I know I haven't been the best all days but I am still trying my best , and I love my profession)

So I am in class X, and I'm a complete fuck-up and I have no idea how to recover from this situation, I have all of my subjects' work incomplete, I have nexttoppers backlogs and as my only source for subjects apart from maths, since I joined tuition very recently, I have no idea how to cover backlogs and do such a vast syllabus, apart from this to add cherry on the top we have attendance as my primary issue, I barely go to school and my teacher is threatening me that when everyone will be on leaves in jan you'll come to school. Please help me I really have to recover from this situation! I really need to cover backlogs and everything...

Tbh if you get something because the gov considers you superior (inferior on paper) and sidelines others to provide you with an opportunity, then you should accept it in a humble way and not be a braggart😭. Like, if you’ve been given this opportunity, then just study instead of making others jealous who scored much higher than you🙏😔
