SunflowersThis is not, as yet, approved for use in the assignment, though it is with SQA.

When the Revised Higher was introduced in 2011, two exemplars for the Researching Chemistry Unit were produced: antioxidants and alcohols.

At the same time, hoqwever, a biodiesel exwemplar was also submitted. Somewhere it went astray, not helpw by the fact that this was around the time that LTS became ES.

Anyway, I have reworked the unit and it is now (Aug 2014) with SQA.
