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?

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
Yeh I think those are correct.
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
