The Core SAC is the only SAC that lasts more than 1 period.
You'll be analysed on your ability to transform data into information for users to understand what's going on between two variables using many different techniques, and your ability on commenting on the relationship between the variables and justifying reasons why it is so. Expect a series of data sheets in which you have to sketch box plots, histograms, scatter plots/linear regression lines/three median lines.
Since the Core SAC covers about 8 chapters worth of material they can't cram everything into 1 period like they would with your module SACs (which are 1 period SACs) so stretching it into 2 weeks would be fair as they can challenge you on everything you've learned so far.
Good luck! dw it's not hard at all
