Which way does electricity flow?

Electricity flows depending on whether you talk about the electron or the +ve charge.

Electrical engineers say
"watch the +ve charge move"
which in exam convention is called:
conventional current flow

Others say
"watch the electron move".

Electrical engineers will draw a diagram with flow out of the +ve terminal on a battery and back into the negative terminal.

Electricity and exam both have a cross in them this helps you remember flow starts at the +ve end.

So a circuit diagram with arrows would look like:
