At top:
-Outside loop:
-Inside loop:
At Bottom:

Fc being Centripetal force?
Yep

Not sure about Inside loop when at the top but others correct
Yeh isn't it fnet=N+W insdie the top of the loop?
since gravity is acting down and the normal is down aswell since the track is above you or is that not correct?

At the bottom, you need equations for inside and outside. It is correct for inside.

at the top those equations are correct at low speed. They are wrong at high speed.
At the bottom, you need equations for inside and outside. It is correct for inside.
I don't get what you mean :S. How is it possible to be 'outside' at the bottom of a loop?

Could you explain a bit further? Even better, do you have examples/formulae for each instance? :D

Yeh is it N=Fc+Fg inside at the top?
And what is the equation for outside the circle at the bottom?
Edit: I think that the equations are:
Top:
Outside: n=Fg-Fc
Inside: N=Fc-Fg (or is it Fc+Fg?)
Bottom
outside:N=Fc-Fg
inside:N=Fc+Fg

Bottom

At the top on the inside the normal for ce and gravity are both acting downards so Fnet=N+W so rearrange for N we get N=Fnet-W which is N=Fc-Fg
