Do you own a car/have a parent who owns a car? Best way to consolidate your lessons is to go out driving whenever you get the opportunity to do so and practice. I've no idea how many lessons i've had now, its my third month of driving and the combination means I feel ready for the practical exam, you don't have to set a certain amount of hours as a limit to expect to be able to drive, its contingent on the individual and the context.
