first thing is to not overthink! and what i used to do was pretend everyone already forgot about it, it worked 95% of the time.

first, go to your nearby weapons dealership. then pick up a 1932 smolenzk rifel, a satchel of grenades, and a 1943 soviet tank. [tanks produced in this era were built to last, so i would recommend using one.] next go to your school, and using your newly aquired weapons... no.
