I'm doing engineering at Rutgers New Brunswick and have a very low gpa of 2.0 and I'm very depressed. Note that half the class gets D's and F's. Rutgers NB has an acceptance rate of 30% and so it is quite selective and half are being failed.I'm thinking of transferring to NJIT to increase the gpa. Does anyone know the difficulty of the engineering at NJIT and also does anyone have an idea of what the average gpa at NJIT is? Any info would be of great help.
