Hiya! After a three week break, I am BACK with more unit tests. This time around: SL quadratics and transformations, and HL polynomials, transformations and modulus. HL students will take  both  the SL test and the HL test. Typical 4 questions per standard that cover a lot of key points you're expected to know for your finals.  AAHL: AAHL MS: AASL: AASL MS: May the odds be ever in your favour.  Andrew  

Hiya! Two more weeks before the N25 exams! For students preparing for mocks, please exhaust all the resources I have published on the website and the YouTube channel . If you need more personalised help, don't hesitate to reach out for tutoring! Today we're back with two unit tests. HL students will take  both  tests. The SL questions cover coordinate geometry, quadratic functions, discriminant and rational functions. HL questions cover polynomial functions, modulus and further transformation (reciprocal). May the odds be ever in your favour.  AAHL: AAHL MS: AASL: AASL MS: Andrew  

Hiya! The school year's starting soon, and for many quadratics is the first topic in the course. Today's post has TWO unit tests - but there's no overlap between the two. AAHL students will take BOTH the AASL paper and the AAHL paper. Discriminant, quadratic functions and composition are some of the topics covered on the AASL paper. Polynomials, Vieta's theorem and further transformations are on the HL version. Same as usual - low floor, high ceiling. c:    AAHL: AAHL MS: AASL: AASL MS: If you're looking for more personalised support, don't hesitate to reach out and complete the form !

Hey y'all! Happy lunar new year for those celebrating it! After a long vacation, I am finally at my laptop to upload the unit tests that I have in the hopper. Today we'll kick off with two tests on quadratics and transformations. As usual, some questions are more challenging than others, and if you're comfortable with all of the questions then you'll most likely get a 7. c: If you're looking for more personalised support, don't hesitate to reach out and complete the form !

It's Tuesday Tests and I'm back with two more tests for AISL and AIHL folks. The AIHL test is pretty similar to the AA tests because y'all need a solid foundation of algebra to do well in the course. AISL is different in nature. I recognise that not everyone needs to master algebra to the same level as AIHL and that you don't really need too much algebra to get a high 7. By this I don't mean AISL is in any way inferior to AASL; it's simply a difference in the focus of the course.  So here you go. AISL: AISL Answers: AIHL: AIHL Answers: Usual TOCs apply.

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 ...
