FS1 - TOC

I've indicated where these topics used to lie on the old specification to make finding practice material easier.

• Discrete random variables (S1) 
• Distributions
• Binomial (S2)
• Poisson (S2)
• Geometric (S5) 
• Negative Binomial (S5)
• Hypothesis Testing 
• Poisson (S2)
• Geometric (S5)
• Central Limit Theorem (S3)
• $\chi^2$ tests
• Goodness of fit tests (S3)
• Contingency tables (S3)
• Probability Generating Functions 
• Properties (S5) 
• PGFs of standard distributions (S5) 
• Sums of independent variables (S5)
• Quality of tests
• Type I/Type II Errors (S4)
• Power functions (S4) 

(S5 was a module that existed from 2001ish until 2006, papers can be found here. It was killed off along with S6/M6. I can't find a spec from back then, but you can guesstimate the content from past papers)
