Andrew's Guide to IB Mathematics Universe

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. 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 students who struggle to access help everywhere on Earth. Happy holidays!

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...

Hey y'all. This unit test is long  overdue; I just couldn't find the inspiration to write a decent unit test on trig relationships. The SL version will be uploaded soon; it's mostly identical to the HL paper, maybe one fewer question and lower "grade boundaries". Enjoy! AAHL/AASL Unit Test: AAHL/AASL MS:

Hi y'all! N24, your exams are right around the corner. I'll do what I can to help you get the best mark possible, but most of the work falls on your shoulder.  Today I'm back with a unit test on Sequences and Series; it's been a while since I last posted a test on this because I haven't found enough challenging questions when putting together this document. Enjoy! AAHL: AAHL MS:  May the odds be ever in your favour. Andrew

Hey y'all! A little different from my regularly scheduled posts, this time around I'm just gonna make some quick announcements! For many, a new school year is right around the corner (or already started!) and some of you have apprehensions going into the course, especially AAHL, perhaps due to your friends and upperclassmen scaring you (they're not entirely wrong) or you just realised you're totally out of your depth since day one (oop-). It's not too late to get help. For new DP1s, a solid foundation of algebra will save you SO MANY MARKS on exams. Every high-performing student will tell you to focus on algebra earlier on because it's worth half of the marks on some questions. Quadratics in trigonometry, simultaneous equations in sequences and series, you name it. The gaps in your basics will come back and bite you if you aren't careful. For current DP2s, lots of you have a hard time with trig functions, equations and identities. Unfortunately, there's ...

Hey there new DP1s (and anyone interested!) A new school year is on the horizon and as a tradition I'll send you a gift to help you prepare yourself mentally for the course: AAHL Foundations of Algebra Unit Test. The same test can be used for SL, though you don't need to tick every single box like the HL kiddos. If you find these questions difficult, it's time to revisit the Foundations of Algebra Unit or ask your teacher for additional work. Don't kick the can down the road; algebra will come back and bite you in just a month's time. Unit Test:   MS:   May the odds be ever in your favour, Andrew

Hey there kiddos! It's been a year since I last posted anything on vectors. Happy to report that it will be changed today!   Go ahead and find the latest set of unit tests below. This set is, hopefully, still difficult but manageable for many of you. AAHL Vectors: Vectors MS: May the odds be ever in your favour.
