Stick to your C152 or C150 until you finish your GFPT. Then do the conversion to the P28A, as for doing it in 1 hour you would have to be very switched on (not many are) stalling is a piece of cake in the warrior as against the Cessna, steep turns are different, forced landings are again different and you have not even got over to 11R or 29L yet, I would expect students to take at least 2 hrs, don't be in a hurry to change if you wish PM me and we will talk.
good luck !
