**The IB SL Flipping Maths Videos** are grouped into:

1) Algebra: geometric and arithmetic sequences and series, binomial expansion, log laws and rearrangements, natural log and e.

2) Functions: Finding domains and inverses, function notation and inverses, vertical asymptotes, solving quadratics using the determinant, basic transformations and sketching quadratics.

3) Trigonometry: Sine and cosine rules, converting between radians and degrees, remembering the unit circle sketching trig graphs, using trig formulae, solving trig equations using factorisation.

4) Vectors: Dot products, unit vectors, magnitudes, vector equations of lines, checking if lines intersect, shortest distance from a point to a line.

5a) Probability and Stats 1: Finding the mean from grouped data, finding the median from cumulative frequency curves, introduction to standard deviation, correlation, Pearson’s Product Moment

5b) Probabilty and Stats 2: Normal distribution – finding probabilities and z values, Bayes theorem, binomial distribution, expected values.

6a) Calculus 1: Differentiation rules – chain rule, product rule, quotient rule. Optimisation, classifying stationary points, kinematics, equation of tangents.

6b) Calculus 2: integration rules, definite integrals, areas between curves, volume of revolutions.

7) Revision Videos: A fantastic collection of detailed videos on each topic in SL maths. Algebra, Functions, Probability and Statistics, Trigonometry, Vectors and Calculus reviewed in depth (each video is about 40 minutes and goes through all core content with worked examples). There’s also a comprehensive GDC review of all techniques needed for the paper 2 calculator exam. Also useful for HL students – you need to know all this as well!

8) Mitch Campbell’s IB SL videos. A new collection of videos made just for IB. At the moment he has made playlists for

a) trigonometry,

b) algebra

c) functions and equations

d) calculus

Most of the videos above are taken from the two fantastic video collections of PatrickJMT and ExamSolutions. Both have even more videos to watch to view topics in more detail.

**IB Revision with** Revision Village

There’s a really great website been put together to help IB students with topic revision both for during the course and for the end of Year 12 school exams and Year 13 final exams. I would strongly recommend students use this as a resource during the course. You choose your subject (HL/SL/Studies if your exam is in 2020 or Applications/Analysis if your exam is in 2021), and then have the following resources:

The Questionbank takes you to a breakdown of each main subject area (e.g. Algebra, Calculus etc) and each area then has a number of graded questions. What I like about this is that you are given a difficulty rating, as well as a mark scheme and also a worked video tutorial. Really useful!

The Practice Exams section takes you to ready made exams on each topic – again with worked solutions. This also has some harder exams for those students aiming for 6s and 7s.

The Past IB Exams section takes you to full video worked solutions to every question on every past paper – and you can also get a prediction exam for the upcoming year. I would really recommend everyone making use of this – there is a mixture of a lot of free content as well as premium content so have a look and see what you think.
