what's the procedure for getting into medical/engineering schools in the uk. is there a test. what about the civil service and the army? and if i wish to be a manager, how do i pay for an mba if i'm like poor.

Medical schools are unlikely to accept applications from people who don't use capital letters.

The army might still take applicants for cannon fodder, but I think even they are getting more selective that they used to be.

Good luck.
