Matematik 2c
Algebra, straight lines, logarithms and statistics: the second course on Natural Science and Technology.
Matematik 2c builds on 1c with more algebra, equations of straight lines, systems of equations, quadratic functions and logarithms, plus geometry proofs and statistics. In Gy25 it is called Matematik, nivå 2c.
Overview
Matematik 2c is usually taken in the first or second year of the Natural Science and Technology programmes. It asks you to handle longer chains of algebra than before: solving quadratic equations, working with systems of equations and using logarithms to answer questions about growth. Geometry adds a new demand too: proving that something is true, not only calculating it.
Many students find that 2c is where gaps from 1c become visible. If factorising or the rules for powers aren't automatic yet, each new topic takes longer than it should. The good news is that the course is closely connected: once quadratic functions and straight lines make sense together, much of the rest falls into place. Statistics, with spread, correlation and regression, is a different kind of thinking and is worth practising on real data. Old national tests near the end of the course show which parts still need work.
What you learn
-
Algebra and equations
Quadratic equations, factorising and rules for powers.
-
Straight lines and systems
The equation of a line and systems of linear equations.
-
Functions
Quadratic and exponential functions, and logarithms to solve exponential equations.
-
Geometry
Similarity, circle theorems and simple geometric proofs.
-
Statistics
Measures of centre and spread, and correlation and regression.
How it's scored
Your teacher sets the grade (A–F) from everything you have shown during the course. The national test is weighed in specially, but it doesn't decide the grade on its own.
How to prepare
- Practise without a calculator: the national test has parts where you can't use one.
- Get fluent with quadratic equations and logarithms: they come back in 3c and 4.
- Work through old national tests that have been released, under the real time limits.
- Write out every step. Clear reasoning earns credit even when an answer slips.
