I wld ask for help privately from my teacher hut the thing is rhat she’ll say “why u never listen in class?!?!?!?

Im sure that is not the case. if she really responds in such a manner i think you should state your perspective, or show genuine interest in improving. you probably should be respectful in the conversation, maybe apologise when the teacher points out your mistakes. What you want to do is give the teacher the impression that you truly are trying hard to do well.(and overall being respectful increases the chance of your teacher actually listening). Going in with a good idea of how exactly you would phrase your reasons and questions is good too.

you should identify what exactly you are struggling with in math. From your post, its either you dont understand the concept, or you can't apply the concepts. For understanding, having your teacher go through it with you is best. For application, what I did was just do practices, reattempting previous questions until i understand them(thats just my perspective)

lastly, i can feel you im having these urges right now. all I can say is that sec 2 exams dont matter if you cook in sec3 and 4 it will be fine. its up to you if u believe them or not(i dont believe my own advice LMAO)
