Just one extra thing I'll add to the advise here is that a consistent seat position is vital. When I first started on the thing, after training my landings Went back to being a bit inconsistent and i couldn't work out why. I eventually realised that I wasn't being disciplined with my seating position. Just aligning the balls is not enough and I needed another reference to make sure I nail it every Time. I personally don't like the recommend seating position that Airbus gives its way too high but that's just me.
