I have solved and attached the aspect sequence chart for 2011 Module 3 question No 11 and also attached the Module 3 question paper.
Kindly have a look and give your valuable comments.
Kindly correct me if I’m wrong.
Note:
1.All the Down slow signals are placed with inadequate braking distance,
2.Consecutive double yellows & Approach Release from Red features are used,
3.I feel there is no use of providing ROL for the signal 111 and 113.
4.It is assumed that the rear signal of 105 and ahead signal of 117 are placed based on the braking distance.

I'll try to have a look at this soon, but at present there is an Olympics on, and "volunteering" wearing a magenta-pink tabbard. This is not the type of question easily answered in such circumstances.
However you are right that the essence of this question is all about signals which are spaced closer together than braking distance. Hence consequtive YY (and possibly a case of consecutive Y) as well as approach release will feature.
I interpret your notes as the assumptions you would have stated in your answer. I think the examiners arranged to have a ROL for a reason, and therefore if your answer is not going to include it I suspect that you would lose some marks. Certainly you should have given a bit more explanation of why you do not consider it valuable.
