After using the hints, I found the Fibonacci question (Q5) of the Step 2 mixed pure quite doable, but I'm not sure I'd have ever figured out the $F_i>2F_{i-2}$ trick on my own.
The solutions for that question have a mistake on the last line. It should be $S<3\frac{29}{60}<3\frac{1}{2}$.
Question 6
Your solution for question 6 has a stray minus sign. It should be $(x_1,y_1)=(0,1)$ and $(1,-1)$.
Question 8
The hints sheet says the expression for $\pi R$ is a cubic in $q$. It should be 'quadratic'.
Thank you!
Thanks again - I'll make the changes Monday. Quite a few mistakes seemed to creep into this question!
Mistakes corrected
And hopefully no new ones added!
