Andrew for Hire - A little more about myself!

-
Hello hello hello! Welcome to the website! If you're here, there's a very good chance you're also in my mocks server . However, if you come from the IB server (I occasionally shared some posts there to get more traffic), you'll see that I have loads to offer. c; If you're interested, please fill out this form:  Andrew's tutoring form . I'll get in touch with you to understand your needs better. Just reach out and I'm more than happy to discuss your particular needs. Group tutoring are also available at a discount, please get in touch! Who am I? I'm a Chemical Engineering graduate from McGill, has a passion for assessments (especially maths assessments) and develops a passion for good teaching. I'm a mock exam writer (duh, I have an entire mocks server) since May 2020, writing papers for both AA and AI every exam season. I've been a session leader and occasionally revision organiser on the IB server for some time now. Here's the link to so...

[AAHL][AASL] (Unit Test v2.3) Quadratics and Functions

-
Image
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: Andrew

[AAHL][AASL] (Unit Test v2.3) Trigonometric relationships

-
Image
Hiya! As the school year's starting for a lot of y'all, it's the perfect timing for a unit test - on a topic that's usually covered in the first semester of DP1. This time, we'll look at problems on trigonometric relationships - solving problems using the sine rule, the cosine rule and the area of a triangle in a wide variety of applications. Some of the items are quite demanding - enjoy!   AAHL: AAHL MS: AASL: AASL MS: Andrew

[AAHL][AASL] (Unit Test v2.4) Logs and Exponential

-
Image
Hiya! It's this time of the year again.   The unit test consists of three standards - simplifying logs and exponential expressions, solving logs and exponential equations and handling logs and exponential functions. The SL and HL versions are very similar, with only slight differences in Standard 2 and 3, making the paper a bit less algebraically demanding. AAHL: AAHL MS: AASL: AASL MS: Andrew

[AAHL][AASL] (Unit Test v2.4) Trigonometric identities (v2.4)

-
Hiya! It's Andrew and once again we're back with my FAVOURITE topic in the entire course - trig identities! You'll have a chance to experience what it's like to be Vietnamese (yes, we take trig equations VERY seriously) and a dozen questions to flex your trig identities muscles. Today's tests feature reciprocal and inverse trig functions for HL and the Identities for All.  AAHL: AAHL MS: AASL: AASL MS: Andrew

[AAHL][AASL] (Unit Test v2.4) Integral Calculus

-
Hiya! After a month's hiatus, I'm now back with the unit tests on integration. If you haven't checked out the new YouTube channel , please give it a like and subscribe! c; Today's tests cover integration techniques, definite integrals and applications of integration, including but not limited to finding areas and kinematics. The HL tests cover HL integration techniques (integration by parts, more advanced substitution and trigonometric substitution), as well as HL applications (volume of revolution, reduction formula and an introduction to improper integrals). Note that you have 90 minutes (instead of 1h) to answer all the questions. Take your time... but also don't! AAHL: AAHL MS: AASL: AASL MS: Until next time! Andrew

[AAHL][AASL] (Unit Test v2.4) Differential Calculus

-
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

[AASL] Booster Set E

-
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.

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

[AAHL][AASL] [Bridging to a 7] Part 4 - Integration

-
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

[AASL] Survival Paper B3

-
Hiya! This is yet another post in the Survival Paper series. Seven questions, seven opportunities to brush up on the basics. Today's test features quadratics, coordinate geometry and definite integrals, besides other topics. At this point, if you haven't yet mastered these basic skills, please go straight to the Survival Guide for a comprehensive checklist of the basics. Same as the last Survival Paper, all papers start with a B means calculator use is expected where appropriate. Survival Paper B3: B3 MS: B3 Scoring Guide: Andrew
