I'm not gonna say it's a bad game, but it really didn't strike a chord with me, and not because I was expecting some sort of GTA in the schoolyard.
The whole time-management aspect - balancing going to class with completing various activities that require you to take advantage of the fact everyone is in class, or otherwise conflict with your schedule is a neat idea and something that doesn't get done often, but it felt less like a puzzle (ala the old School Daze) where you would treat the objectives like separate pieces, planning and executing attempts each day, and more like a whole bunch of stuff put out there to stop you accessing all the content too quickly, with a story layer thrown over the top that makes you feel perpetually rushed.
And unless you really want to roleplay a snotty jerk, you're not going to find the player character likeable or relatable. I mean, perhaps there were opportunities for some redemption further down the storyline than I got to, but I found most of the setup tedious and relying on tired stereotypes. On the one hand, it's Rockstar, what do you expect. On the other, they managed to write a love letter to westerns with Red Dead that grabbed you from the outset. I just didn't feel any depth to Bully's setting or characters.
It has been a long time since I played, but I remember restarting twice, and really trying to give it a good go before I dumped it.
