[AASL][AAHL] Binomial and distributions / Binomial, counting and distributions

-

Hiya!

The latest set of unit tests is out - binomial, counting and distributions for HL and binomial & distributions for SL.

This combination covers all things combination - after all, binomial distribution is also a combination exercise.

For HL, the test has four sections and lasts 90 minutes. Calculators may not be used in the first 45 minutes.

There's a question on using binomial expansion on trinomials, a question on making seating plans and a question on coffee.

For SL, the test lasts an hour and students may use technology for the entire test. 

If you're looking for more personalised support, don't hesitate to reach out and complete the form! I'm @adventurousandrew on Discord.

[Survival Guide] AASL Version

-
Hello hello hello! I am now back with a fancy project - the ultimate Survival Guide for AASL. If you're struggling and you want an all-in-one Survival Guide, this  is it! What's in the Revision Guide? Packed inside this booklet are a series of statements for you to check if you're prepared to get a solid 4 (or even a 5!) on the official exams. You'll also have questions on the right column to check if you know what you're doing. Answers not included. I know y'all don't have time to do all the stuff in hundreds of pages of the RG, and it's hard to find a revision checklist like this online, so I might as well make it available for everyone interested. c; Disclaimer I've tried my best to only include topics that usually pop up quite early on the exams, but do not sue me if the questions on the exam do not exactly match with my preds.  Compacting two years of content in a 15-page document means some content will be left out deliberately  (you don't ...

Hiya! Thank you for visiting my website. There's quite a lot of resources I've published over the years, and I know it can be overwhelming at first. You don't know where to start, what's the difference between various types of tests, and where to find everything. Look no further - this is the one-stop-shop for all your resources.  Unit tests: designed to stretch the best students but weaker folks should have enough opportunity to secure an A (in Unit Tests v1) or an A2 (in Unit Tests v2). The number of marks is not indicated for each question - the focus is on getting the easy questions completely correct , not a game of "how much partial credits do I get". To get grade (level) 7, you'll need to be very efficient - working well under time pressure is one of the things I'm also evaluating here. The unit tests for each topic can be found below. Algebra and functions (Topic 1 and 2)   Geometry, trigonometry and vectors (Topic 3) Statistics and probabi...

A collection of topic tests that I've ever written on the website. Unit Tests Occasionally featuring questions from endless inspirational sources. Answers included. Version 1 Nombre complexes (AAHL seulement)  Complex number. The test is in English, don't worry. Contains some wonderful questions that might require the use of integration. Logarithms (AASL/AAHL)  Logarithmic, exponential and rational functions. Further transformations for AAHL students. Proofs, binomial and more (AASL/AAHL)  A list of miscellaneous topics that don't fit anywhere. Quadratics (AASL/AAHL)  Combined algebra and quadratics - an updated version will arrive soon. Quadratics (AISL/AIHL)  Slightly different from the former because of the emphasis of the courses. Sequences and series (all four courses)  Covering two types of series studied in depth in IB: arithmetic and geometric. Knowledge of logarithms was required if memory serves me. Version 2 Please note that binomial expansion ...
