Andrew's Guide to IB Mathematics Universe

Hiya! This marks the start of Unit Test v2.4! We'll kick off the series with a relatively straightforward test: Introduction to Calculus. This test contains questions on basic differentiation and integration, limited to power functions. Questions on tangents and normals are also included, as well as initial value problems and various applications. Use this test to identify the areas that you'll need to focus on before the test.

Hey y'all. It's almost the end of February. For November students, most likely you'll have prelims/mocks coming up. For May students, the exams are right around the corner. Enjoy the last time you'd have a lot of time to revise before taking your final exams - quite likely you won't have this in uni. Feb also means Andrew's mock season's coming up. The mocks will (tentatively) take place on the first week of April . The results shall be available by mid-April, allowing us (a fellow proofreader/grader and I, most probably) sufficient time to return the scripts to you. I'll also host a series of sessions on the IB server; highly recommend to check it periodically for updates. I'm seriously considering a live "survival guide" session (or probably several) and of course, the regularly scheduled trigonometric functions and identities. Now back to the unit tests. Today's tests feature sequences and series, with the third standard specifically...

Complex numbers is, frankly, quite complex at times. This is arguably one of the hardest topics in the course, so I'd like to expose you to a wide range of questions that may seem challenging at first but they're all within your reach. Enjoy! AAHL: AAHL MS: A couple announcements. (1) We're in the last phase of writing the mocks before the papers are shipped to RShields for proofreading. Details to come, but mark your calendars: the mocks will (probably) take place in early/mid-April, allowing sufficient time to actually mark the submitted scripts and provide feedback on the performance. (2) Be on the lookout for revision sessions on the IB server: as usual, I'll be doing a session on trigonometry. Might split it into two to improve students' attention, idk. It may or may not be recorded. (3) Tutoring slots are still available if you're looking for focused practice before the exams. DM me if you're interested and I'd love to discuss the details with you....

Hey y'all! Nothing screams Andrew more than ridiculous trig questions. Well fear not, I'm back with the unit tests on trig functions, to be taken right before the almighty trig equations! AASL: AASL MS: AAHL: AAHL MS: Just a little note: if you're interested in tutoring, please don't hesitate to get in touch via Discord @adventurousandrew or the tutoring form . I won't bite, promise. -Andrew

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: AASL Quadratics: AASL MS: AAHL Transformations: AAHL MS:

What better way to start the year than a couple unit tests! Today I'm back with two unit tests on Integration! Different from v2.2, HL students only have to take one single test that lasts 90 minutes. The SL papers contain questions on indefinite integrals, u-substitution, definite integrals and area between curves. The HL papers contain questions on all integration techniques and applications.

Hi y'all! This might be my last post before Christmas. A Christmas wouldn't be the same without a Christmas log.   To celebrate Christmas, here's my gift for y'all. Two sets of tests on logarithmic and exponential functions. The tests focus on logarithmic and exponential functions, providing students with valuable practice for their upcoming exams. The test covers key concepts such as logarithmic equations, exponential growth and decay, and the relationship between logarithmic and exponential functions. Use this test to assess your understanding and identify areas where you need further review. Pay particular attention to Standard 2, logarithmic and exponential equations, as students tend to struggle with the topic. AAHL:   AAHL MS:   AASL:   AASL MS: Watch this space, as there will be more exciting things to come next year. I'm thinking of making more content for lower attaining students, which is usually not our demography here, but that might be useful for studen...

Hey y'all! Christmas is right around the corner, and for many finals are quickly approaching. For some unfortunate souls, finals won't take place until mid January. And for DP2, it can be the last time to change your predicted grades. I just have a couple humble tests on differentiation and applications of derivative here today. Very similar structure to v2.2, but arguably a little shorter, giving you some time to breathe. :P Here are the papers! AAHL: AAHL MS: AASL: AASL MS:    As usual, may the odds be ever in your favour and happy holidays! Andrew

Hey y'all. My love for trigonometric identities just got me all hyped up and make the third round of Version 2 trig identities tests. The content is similar to last time, with a couple more questions for the SL students to give them more opportunities to show off what they want. The HL papers are long and demanding as always. Enjoy! AAHL:   AAHL MS:   AASL:   AASL MS:    

Assessment Theory 101: Compensatory vs Mastery Model Hi everyone, This post is more targeted at fellow teachers, tutors and assessment enthusiasts, but of course students are welcome to learn more about the various grading systems. Today's post is on compensatory model vs mastery model. For simplicity, compensatory model is often used in external assessments in many countries, but there's nothing stopping us from adopting the mastery model on end-of-unit assessments in class. To keep it simple, let's consider a short end-of-unit test on logarithms consisting of three topics: use properties of logarithms to simplify expressions solve exponential and logarithmic equations solve modelling problems involving exponential and logarithmic functions Each topic is worth 10 marks, giving a total of 30 marks for the whole paper. The pass mark is 50%, so 15/30 marks. Notice that there's a LOT of paths that would get students to 15/30. To illustrate my point later on, we'll cons...
