You have a proper reason to dispute if the other teacher that's marking rejects then since you wouldn't have prepared other options xD Yeah represent all of us who can't/couldn't choose anime as a related text! Good luck both of you with the assessments :D
It might be time to move schools 😔 But anyways I too am more suprised there is no limit for you in regards to fiction and non fiction Etho_x, so lucky! :O My school probably wouldn't reccomend... You should have recorded evidence of the teacher that gave you permission!
It'll become much better once you get to the middle of the year, but not much better with trials and HSC closer I guess xD On the bright side, last year you'll ever have to worry about assessment tasks for subjects that you don't enjoy :D
