The pinout for BC550 / BC560 is:

C-B-E if you look on the flat side, with pins looking downwards.

Pro: If you look at the transistor from the top, it's shape reflects
the schematics symbol. Easy to learn.

Con: If you solder the transistor into your circuit backwards,
C and E are switched, and you might get strange errors because
you still have a working transistor, but with very small current gain.
(Harder to test for an error.)
