A friend of mine had the same problem, he just could not get which way to turn the wheel where reversing round corners, his driving instructor gave him a kids toy jeep with working steering and told him to try replicating the parking and reversing round corner manouvers with it, as it would give a clearer veiw of what happens when you turn the wheel when looking from above instead of trying to work it out while in the car and stressed.It worked well for him and he swears by it and tells anyone having the same problem to try it :-)
