we were able to do our optional units alongside the college taught ones. just tell the assessor what you are doing in the plan when she visits.
we had all the standards when we started the course, do they still do this, so we had the bits for the optional units so we could start on them straight away if we wanted to.
maybe this would be an idea, work out what you want her to see and get her to write it up now then you will have another unit under your belt.

hope thismakes sence
