The fastest way to do that is volley active players until you have 4b or so. Then, do volleys from 1b to 4b and that will make you a lot each volley. Once you have at least 20 dorms you can start using extra credits to help you. This is because the amount you get for them start being worth it at the 20th dorm. I recommend you wait until you have 32 dorms to sound extra credits, but definitely do not spend the before you have 20 dorms. I would skip tier 3 because this sacs money and cuts money off your cost to LCBC. (about 192.8b from scratch) _Warrior
