Tile breaking when cutting

[Susiequ]

Morning, I am tiling brick bond 300x100 ml bevelled tiles in a kitchen. I have a double socket to go around. It is in the middle roughly of the tile. Tried it twice, scored it around the three edges. There is only about 25 ml on the top. Use cutter to take out strips. As I get to the last 2-3 strips it snaps on the corner.
Any suggestions please to get a successful result?

Anglegrinder, decent blade, go slowly and be gentle.
