After your initial volley and upgrade, you should find an inactive farm, and farm them while also volleying new people that post on campus to like 20 million so you don't risk keeping, and once you have about 350 million, start guiding and volleying new people to 5k cs, THIS is when you should stop farming your inactive person, and start/continue doing jobs because jobs have a 2% chance of earning you an extra credit, and you can save them up, once you have 15 you can exchange them for cash, but I recommend you wait until you have a good amount of dorms, # of dorms you have before you start exchanging them is up to you, but once you have say 31 dorms you can get a little bit over 1 billion dollars for every 15 extra credits you exchange with the nurse, the nurse can be found by clicking on store on your home page, and then on the top right there is a nurse that says "touch me", from there you can exchange your credits for cash, another way to get credits is through in-app purchases, also located where the nurse is.

This is my first "guide" per say, let me know how I did, I kinda just threw it together so that's why it's all clumped up Blake_s
