The admit rate for transfer students to MIT is EXTREMELY low. Latest common data set shows an admit rate of 4%. I would not get your hopes up.
WPI is a fine school. My daughter just graduated from there last May. She very much enjoyed her time there. The classes were good; she made some really great friends. Worcester isn’t the greatest city but they found plenty to do there.
I went to MIT many moons ago. MIT is definitely a challenge and you learn a lot; work with great people, etc. But, from talking with my daughter, you do also at WPI. If you take the attitude that you are going to a school just to transfer out, then it makes it very hard to enjoy yourself (and do well) while you’re there. Go to WPI; plan on staying; enjoy the experience.
