Just keep opening dorms and putting in better dorm members,you get there eventually u also can do jobs to get a rare extra credit drop that u can use to buy speakers in the shop area
Maxed out their level?(level 4 is max) and how can u afford a wrestler at your stats? Get the computer hacker and the juice jokey in all dorms then turn them into Syfi and wrestlers (I'm 7 wrestlers 7 Syfi all averaging 2-3 in level)
Your 700m,that's actually a fairly high price,probably not worth it for them to volley u instead ask them to teach you
They volleyed me that high. I need them to do a drop volley for me! But anyway, all my dorm members exept wrestler is level 2
