If you continue to work hard it will pay off afterwards. For now, in my opinion, you are more comfortable drawing the head, the eyes and hair than the body. You should practice more body poses and understand how the muscles and bones work. The body lines are a bit rigid, try to make contrasts in the linework But with time and practice you will get better, keep on practising.
So it's fine for you being in a school with incompetent teachers, learning nothing (and paying for it)? Just because in that school you had fun the years before? So it's alright if this year is beyond terrible and you just have to be fine with it? If that's your position, let me tell you that next year will be even worse.
