Ok, pretty much a summary of what's come before-
Dunno what people were talking about in terms of being a metre away from the lines, give yourself as much room as possible away from them in order to correct any errors you might make.
Line up a point of reference (I use the door handle on the left hand side) in line with the third line before the space.
As soon as you hit that line, very quickly turn full lock to the left. You can do this manoeuvre pretty slowly, as long as you keep checking for cars.
Keep going with full lock until
i) the back of the car is straight in the bay
ii) you can see in your side mirror you are about a foot from the line (you'll get used to the judgement of this with practice!)
Once you have reached this point, straighten up.
You can make adjustments while backing up, so try to find a space without other cars around if possible.
Oh, and remember to look around (particularly out of the back window) and not rely on your mirrors too much, because you'll be marked down for effectively not looking where you're going (even though you can't see much out of the back)
Hope some of this huge post helps!
