Military Electronic Systems Engineering MSc course ; part-time

Hi,
I am wondering what it is like to study the Military Electronic Systems Engineering MSc course part-time whilst working full time.
I have a few questions, hopefully someone can help..
How much of the course may be done remotely?
How close together are the 2-week modules placed? (I believe each module to be around two weeks but please correct me if I am wrong.
How easy is it to receive help from lecturer is studying remotely and part-time?
Is there anyone who may currently be studying the course that could be available to talk to and ask a few questions?
If lectures/modules are required to be taken in person, who/how is accommodation set up for those temporarily travelling in from elsewhere?
Finally, is a Physics with Astrophysics BSc Hons an acceptable qualification for entry?

thank you in advance for your help.
