I wanted to refresh my bartending skills and i found a great app that i could
get the free workbook from a professional bartending school and they even had
another app where i could take the final exam and get certificate all online
so i could study on in my spare time. Got the certificate and used it to get
my first job as a part-time bartender.
Here is the page i found:
