Is it possible to transfer from a lower level no name four year university (accredited) to a top 50?

Assuming you apply as a junior transfer (for the final two years), maintain a good GPA (3.8 or above) and you do a lot of volunteer work and ECs. You were a B student in High School.

Is it possible to transfer from a tier 4 or tier 3 school to a top 50 University like Georgetown, Washington U in St Louis or Vanderbilt?

YES, how many times are you going to ask? stop second guessing yourself and stop annoying everyone on here.
