MVC and BVC experience

What experience or knowledge of MVC and BVC do you have? 
Did you have any negative experiences? Was it possible to prevent it?
Did you have any positive experiences? Why did you memorise it?

What is the difference in what people expect from public care vs private care?

Please shear your expeirence with me as I need to make choices soon and I dont know what to expect from these institutions. It would be great help.:
