S4 is significantly easier than S3 in my opinion.

S3 has some slightly difficult stuff like inferring degrees of freedom from a table etc, whereas S4 focuses on distributions, the concepts of power and errors are easy (the graph questions in S4 are fun too!).

and I scored 94 in S4 compared to 82 in S3. :h:
