Another very good attempt. You have grasped probably the most important part of this one - the tie up with 212 points.
I'm not sure on this one - should (BR or 212N) be in both the N>R and R>N TC clear. I thought it should be because whichever way 211 are set, if 212 are R, and there is something on BR, would we want 211 to move?
The only thing that I think you missed is that you identified 137A(S) and 144A(S) as calling the points N>R but you then did not enter them as routes required to be normal in the R>N (and hence missed the sectional release conditions).
Otherwise, what you out was what I would, so assuming I am not completely out of it, you should be pretty confident.
