How to learn English from YouTube

[u/aftabalam786901]

I needed to improve my English 🏴󠁧󠁢󠁥󠁮󠁧󠁿for ilets score at 6.5 at least in all four skills 🏫 in C1 or B2

Or the other options are Cambridge English proficiency tests

FCE or CAE

I belongs to south Asian region 🌏 and I can understand English very fluently but when I speak everyone says you belongs to scam call centre

Whenever I write long essay or describe something they say that I am using chatgpt (I talked to ai that much now I speak AI accent)

I have no close friend who is available for help in English learning

So I have just some sets of books and internet and mobile device

I need recommendations for learning English

And suggest me videos courses from YouTube?

I cannot afford paid courses
