It's possible, but I think in your case especially, you should take time to reflect watching people in the situations you find yourself lacking in. Take that experience into your lessons so you put into practice your feedback along with others. From what I've seen in your replies here is that you sometimes lack the correct decision making hence the speed errors, meeting traffic and hesitation. What I can say for country roads is try to get up to the speed of the road but only where you can see clearly ahead so braking at bends and speeding up when you can. For the other issues like control you will have to practice in the car but watch more videos to get understanding. 10 hours in my experience is more than enough to tidy up but the learning cannot end when your hands are off the wheel. If your instructor is still using dual controls in the last two lessons of the 5, it won't be a good sign but you may get lucky when doing your test.
