Simulators are used in two ways, to teach new skills and to practise emergency handly.
There are no sims as such at EFT, not really any point I suppose, as there are fewer emergency drills and they are easily practised in the Tutor. Also the new skills are better covered with instructors in the aircraft thoroughly.
BFJT has a couple of sim domes. With a more complex aircraft come more in-depth emergencies, also there are many more new skills to pic up as it is a long course, and sims can really save flying time and running costs.
To be honest, Microsoft Flight Sim isn't bad, and I understand the feeling that you need to try and get ahead with flying training, but the courses are designed to be progressive. They should take someone who has never even seen a cockpit and make them a capable operator. So chill for now, work hard at ground school, and you'll be fine.
