Elrehab,
Hey doll welcome to the world of being a hostie!! Its amazing how you dont realise the amount of work until you become one its waaay more than just serving tea & coffee. You are pretty much a safety officer/first aider/custy service rep/face of the company. EP's and learning aircrafts/procedures is def gruelling an easy way i remembered things was using butchers paper & writing poems/acronyms and putting on my walls and alot of highlighting! If anything once you're online everything comes into play & you'll be surprised at how natural everything becomes. Make sure to eat well & drink plenty of water!
Best of luck
