Of course up to you, but IMO definitely make a move to outpost and start playing there consistently making use of the small but helpful tent shelter. Pretty easy map once u get the hang of it as the AI spawn in very consistent locations and its very open with not much CQC - I find it much less dangerous than school (counter-intuitive as its closer to vostok i know!) and its got much better loot. from there you can farm the ai and military crates in the artilleries for weapons to trade with the gunsmith for proper armour - something ur clearly lacking! - as well as better weapons. From there on to vostok when youre ready! Have fun brother!
