a past student here
The only tip I could give you is to run away and never look back. Even other CUNY schools would be better than Brooklyn College. But it would be best (if it is financially possible) to avoid the entire piece-of-garbage CUNY system. If you have to attend a CUNY for financial reasons (after all, that's the only reason that can justify choosing CUNY), then you have to mentally prepare yourself for it. You will not learn anything. That's just a fact. You will certainly not be taught anything - you'll have to teach yourself. This isn't necessarily too bad a thing, since all of the professors could care less about their students. Do not look at the full time professors' salaries online - your blood pressure will skyrocket. Kiss up to the administration and staff, because they will make your life miserable in every way imaginable. Finally, all I can say is good luck. Bite the bullet, and prepare for a four year sentence without the possibility of parole.
