Hiya! This is the second calculus test in the Unit Test v2.4 series. The first two standards for SL and HL are identical, but the grade boundaries will be a little easier on SL.  The first standard is on differentiation techniques, testing your ability to use the chain rule, product rule and quotient rule to find derivatives and solve simple problems. The second standard is on applications of differentiation - graphical analysis and optimisation. The third standard, HL differentiation techniques, focuses on implicit differentiation and higher derivatives. AAHL: AAHL MS: AASL: AASL MS: Andrew  

Hiya! Last set of papers before M25! Two reliable papers written in a similar style to the official papers. All started real straightforward but there are a couple twists at the end! Both papers test major topics from the course, with an appropriate level of difficulty/cruelty at the end. Not too much to question your life choices, but hard enough to keep you on your toes.

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. AAHL: AAHL MS: AASL: AASL MS: Andrew  

Part 4 of the Bridging to a 7 series: Integration. Never underestimate IB examiners' creativity. They'll find new ways to weave the topics you least expected into integration questions, way beyond what you're expecting.  Today's discussion is on integrating what you've learned to solve new problems. Be alert for symmetry. Make sure your trigonometric identities are up to scratch. And of course, your algebra has to be solid. Andrew
