Why would he do that? It could be in the 2016 exam... If you want to see the difficulty look at past exams.

Here's a question that was scrapped from 3U because it was too mark-heavy.

$$By using the substitution $ u=x^2+\frac{1}{x^2}$ , or otherwise, evaluate $ \int \frac{x^2-1}{\left ( x^2+1 \right ) \sqrt{x^4+1}}dx$

Here's a question scrapped from 4U because it was too easy.

$\\ $Two cars $ A $ and $ B $ move around a banked track with radius $ r_1 $ and $ r_2 $ with banking angles $ \alpha $ and $ \beta $ respectively such that $ \alpha + \beta = \frac{\pi}{2} . \\\\ $Let the velocities such that car $ A $ and $ B $ experience no lateral forces be $ V_A $ and $ V_B $ respectively.$ \\\\ $ Show that $ r_1r_2 = \left ( \frac{V_A V_B}{g} \right )^2$
