I’d like to add to your points 4) Graduate programs are indeed different from Post Graduate programs. Before your doctoral degree, you were given a question and asked for an answer. Perhaps sometimes, you were also given questions for which known answer existed. In your doctoral degree, you will most likely come up with the question and the answer. That’s a shift of mind, you may need time for adjusting.
