Wanting to apply for both Aerospace/Aeronautical AND Mecanical Engineering?

I'd say they are both equally as hard to get into, but if you are of the right calibre you shouldn't have any problems. On my UCAS, I applied for two general engineering, one aero and two mechanical engineering courses.

You may also want to check out the third and forth year optional modules for courses you are looking to apply to. A lot of unis cater for aero modules in mech eng degrees and vice versa. Some unis even offer (like Southampton for example) degrees called Mechanical Engineering with Aerospace and in this, your third and forth years are more focussed on aero than a normal mech eng degree.

At the uni I'm at the first year between aero and mech are almost identical so choosing one over the other doesn't mean you'll miss out on certain areas. Of course from second year they diversify but some unis allow you to switch courses after the first year due to their similarities. It may be worth e-mailing loughborough about this as you can apply to two different courses at the same university, but if they do allow the switch after first year, you may only want to apply to one course of the two and apply to another course at another uni in its place.

Okay I see what you're saying; thanks alot this was very helpful.

Where did you apply and how many offers did you get just out of curiosity? Also how did you set about writing your personal statement catering for all the different disciplines you applied for? Or did you just write a personal statement generally catering for Engineering as a whole?
