(this is a step-through-step explanation) (it doesn't usually matter a whole lot but just giving you the best options)
First you should join the drama club
Then when you introduce yourself only choose the BOTTOM/LAST option
When you get to the break, always talk to America
(talking to america) choose "HONESTLY, YOU'RE THE COOLEST PERSON HERE"
Then choose "I'M GOING TO GET A SHIT GRADE"
(taking the TEST) choose only MIDDLE/SECOND option
(TALKING to America) choose "SURE"
(when STUDYING at America's house) choose "DO YOU LIKE ANIME"
choose "NYAN NEKO SUGAR GIRLS"
choose "DO YOU LIKE 80'S MUSIC"
When you get to break without America choose to go to CLASS
choose to go to AMERICA, RUSSIA, and UKRAINE's group
(TALKING to the group) choose "PLEASE CALM DOWN, WE'VE GOT TO WORK ON THE PROJECT, RIGHT"
choose "CALM DOWN, PLEASE"
choose "LET'S USE RED"
choose "YEAH, MAYBE BLUE'S A BETTER OPTION"
