ST: where and how

[andreox]

Hey hi

here it's an italian student writing.
i'd like to do the FP somewhere in UK and then maybe the ST as well.
do you guys mind some questions?

what would i do if after 2yr FP if i do not get to the CST?
how hard to get in the cst?
is that true that the exam to get in CST or CMT costs 800p?

What about colloquium for ST?
what is that about?i know the compare applicants CV..but..what happens if CV is basically the same?do they give you questions/tests/clinical case to solve?

one more question: could it be me applying for CST or ST in different hospitals in the same year?

thanks guy for your help
