What should I do as a HSC 27 batch student?

Hi I am currently in class 12th BV. I just barely passed 11th few days ago. I preferred studying offline. I had two teachers - 1. Medical student who teaches Biology, chemistry and English. 2. Uni CSE student who used to teach Physics,HM and ICT. He used to teach well but he got sick and stopped teaching. After that my mom kept 3 teachers through media but none of them taught well. I literally still haven't finish my class 11th syllabus and even failed in physics and HM. Now no uni student want to teach a full syllabus because they passed on half syllabus. I have ADHD so my attention span is very low. When I sit to study alone I need to constantly listen to something. But Infront of my teacher I can pass upto 1h then my head starts hurting bcz of migraine. So what's the best option for me right now?
