Thanks for that. I don't know how you found that information as I spent a lot of time looking.
These are the available units with dates;

The units candidates must take to be eligible for a cash-in (award) are outlined below. (

No grade can be issued unless the appropriate cash in code is entered. Once a candidate certificates a Mathematics subject, the units that have been used to generate the award are 'locked' to that title (even if the candidate retakes them). Units 'locked' to a subject title through a previous certification may be 'unlocked' by re-entering for that same title.
For example,
if a candidate who has already certificated AS Mathematics wishes to resit one of these units they should be entered for that unit and AS Mathematics to ensure the other units that contribute to AS Mathematics are available for certification.
Mathematics subjects certificated before the end of a course should be re-certificated at the end of the course. For example, if a candidate who has already certificated A level Mathematics takes three more units and certificates AS Further Mathematics without re-entering A level Mathematics, the grade for AS Further Mathematics will be generated from those three units. Re-entering A level Mathematics ensures that all units are available for re-use and that the grades for both titles are based on the optimum combination of units.

Not sure I fully understand this, in particular the 1st example.
From my understanding, I can sit these exams whenever I want (based on their available dates).
What is 'banked under the candidates UCI?'
So I can sit whatever units I want and resit whatever units I want. Resit grades wipe the previous grade for that unit. Once I have sat all the required units I can then ask for my Title which are based on the best grades for each unit.
Am i reading this correctly?
