[AAHL][AASL] Tuesday Tests: AA Quadratics

Hi cuties,

It's Tuesday and I'm back with two unit tests.

This time around they're on quadratics for AASL and AAHL.

For many of you, the first unit of the course will be quadratics. Despite its name, there's stuff on the common topics you'd see in the first few weeks of classes, like standard form, surds, index laws, equations and simultaneous equations.

If you know me, it's not the first time I've said these words: algebra is the most important thing you need to do well in AAHL. The same thing can be said for AASL or AIHL. Other topics are important too but everything falls apart when the algebra skills are lacking. Algebra should be a natural thing like breathing, because you won't survive a day of AAHL without algebra.

NB: In some schools, your permission to stay in the course depends on how well you perform on the first test, probably 3-4 weeks into the course. We'd need WAY more than 3-4 weeks to cover the content on these tests, so you need to have the majority of these prerequisites down the belt ready to go at any time.

Without any further ado, here are the tests.

Usual TOCs apply.
