Yes, have you checked the cuts won't be little slivers at the top and bottom of the wall? Measure a tile height, then measure down from that wall the same height of the the tile, set your laser on that and check that the top of the top of the tile aligns perfectly with the top of your wall, baton then tile up. Once it's dry remove the baton and fill in the screw holes with sealant then work your way down. If the tiles are heavy I would use the baton method again.
