To decide where you’d hide will depend on what you know about those zombies: can they climb? can they walk up stairs? can they open doors? are they afraid of anything - water, fire and so on? That information will guide you to your hiding place.
The same goes for the top-five things you’d bring to stay alive. You need something to help you fight the zombies. If they are afraid of water, then bring a water gun; fire then a blow torch. But among the five things, you will need food and water and perhaps medical supplies.
I'm not going to question this but, me ,being myself, would most likely find out their weakness in this situation because everyone has a weakness. Zombies can't move fast because they are technically dead so yea I would suggest being quick on my feet and having an action plan. Since I am in school I wouldn't get sharp objects because they are already dead, but if i was to do so I would sneak to the science lab and grab some chemicals and safety gear for the purpose of me not harming myself. I'm alone because in this case......trust no one so yea. I would suggest getting things that don't make noise and to be quiet. Get something to mask your scent like garbage, so they can't smell you. I don't have any top 5 things though.
