To avoid me breaking any 'SQA laws' about not sharing advice on how to pass your unit assessment, I can't provide help on here. We will have to wait until Monday now to discuss the unit assessment WHICH WILL BE ON LABOUR REFORMS.
Here is another helpful PDF I got from someone a few years ago, which has some good analysis on Labour Reforms. (Big File ) Download Labour Reforms 1945-51
The essay you'll do on Monday is from the 2015 Paper - Go to page 54 of this SQA pdf to get the marking instructions for the essay. Page 4-6 will remind you how to get the marks.(http://www.sqa.org.uk/pastpapers/papers/instructions/2015/mi_NH_History_mi_2015.pdf)
