Best advice I could give is to "stick at it".
If you are following what you are taught then it will happen. I spent many an hour circuit bashing during my training. I would nail a greaser and then the next one would be a nightmare. The instructor said that one day it would just click but it never did. After many hours in the circuit I thought he was just trying to make me feel better, but you know what ? one day it just clicked !
You will master it, I promise.
Good luck
