How do I convince my mother to let me enroll in an online school?

I am midway through 8th standard, living in India, and honestly, the education just doesn't seem up to par. The teachers actually know less about their subjects than we do, and the atmosphere is just unfriendly. I proposed the idea of online schooling to my mother recently, as well as all the research I've been doing about the pros and cons, available schools and homeschooling laws in our country, but she's convinced that it won't offer me the same opportunities and education that a public school would. How should I convince her that I am quite sure that this is the right decision for me?
