• Challenge: Students had to realize that the line of intersection is parallel to the cross product of the two normal vectors. Many wasted time solving three equations simultaneously rather than using the cross-product shortcut.

Common Pitfall: Forgetting that ( \cos^-1 ) has range ( [0,\pi] ), not ( [-\pi/2,\pi/2] ).

Correlation & Regression: Analysis of scatter diagrams and calculating product-moment correlation coefficients. Key Educational Resources

• Challenge: The sheer length of the working. With many branches, the probability of a calculation error was high. It required neat presentation of the tree diagram to avoid logical errors.
