Prevent a question from be randomly selected twice from a question

Cheers Ashley, I can certainly share a file but perhaps I need to define what I am trying to achieve better, and you can tell me if it is possible using banks or not. If you would still like a file after this I can definitely attach one.

Issues are being experienced when publishing to all formats (not just HTML5).

Challenge 1: I have a bank of 5 questions and I want students to attempt all of them in a random order with no questions repeated.

Challenge 2: Same bank of 5 questions and students attempting all 5 but this time I want Question 1 to appear first, then I want a random selection but Question 3 must appear after Question 2. (in this case an attempt order of Q1, Q4, Q5, Q2, Q3 is fine, as is Q1, Q2, Q3, Q5, Q4 etc).

If you could provide some guidance on how to achieve these two challenges I'd be very appreciative.
