>>6 Zombies are an interesting scenario; melee weapons are preferred, though firearms are possible if: A) You know how to use it and can hit what you aim for in the first shot.
B) You possess the necessary ammunition to make it count.
C) You always have at least three escape routes available and are fast enough to utilize them properly.
But that's only when confronted; your best bet is to stay out of sight and earshot, notably the wilderness is the best option. As long as you know your basic foraging and/or hunting skills, you should be fine. If not, survival will be a lot more difficult. You can fix this yourself, however, so long as you're committed to furthering your survivalist tact. I can't teach you everything, but then again, I'm pretty sure that's what the web is for. Just use it while you can. The internet won't last long if ever the world starts to burn.
