The NCEA Level 2 Maths examination is a pivotal point for students in New Zealand schools. It's crucial to grasp the significance of this level, where students are tested on their understanding and application of various mathematical methods and topics including algebra, calculus, and probability.
Understanding the NCEA Level 2 Maths syllabus is the best way to prepare for the exam. Knowing what you'll be tested on, how questions are evaluated, and the conditions for your assessments puts you in control and ensures you're well-prepared.
How to Understand NCEA Level 2 Algebra Questions
Algebra is one of those mathematical subjects that students will initially find challenging. After all, we spend our first years learning about mathematics as the subject with numbers, and now, suddenly, we're expected to get to grips with the fact that some numbers are letters.
Breaking algebra down into manageable sections and concepts can significantly ease the learning process and boost your confidence.
Look at the New Zealand curriculum for a better idea of which algebraic concepts are covered and what skills are expected of students. At Level 7 (Year 12 or NCEA Level 2), students will learn about rational, exponential, and logarithmic algebraic expressions.
By this stage, you'll likely already be familiar with a range of algebraic concepts and equations, including the ones that will feature on your exams. Generally, you'll be able to form and use linear and quadratic equations, understanding how to use them and when.
Don't worry too much if all of this is new to you. You'll be able to get a better grip on them by looking at NCEA Level 2 Maths past papers.
Understanding any question, including those in your maths exams, is by breaking down the question to understand exactly what you're being asked to do.
Use a highlighter, pen, or pencil in an exam to highlight the key information and keywords within a question. From there, you can establish what the constraints of the question is. Your answer has to include these constraints.
Constraints will change depending on the situation, such as whether your equation remains with positive indices, contains whole numbers, or is written as a single fraction in its simplest form.
It's essential that you understand these limitations. After all, you can easily lose marks by solving the question in a way that wasn't asked for.
Once you've read the question and understood what an examiner will be looking for, it's up to you to work out which concepts you need to use. In some cases, the question will tell you, but in other cases, you'll be expected to apply your theoretical mathematical knowledge.
How to Understand NCEA Level 2 Calculus Questions
Calculus is one of the biggest leaps in mathematical understanding students undertake. This part of mathematics is regularly the one that students complain about and is often the hardest for them to understand initially, causing them to bemoan why they're even learning it in the first place.
However, NCEA Maths Level 2 is critical even if you don't go on to directly use the concepts taught during it.
According to the New Zealand curriculum, students need to learn how to solve problems and model situations through their understanding of calculus. This can include sketching graphs of functions and their gradient functions while identifying and describing the relationships between them.
That's not all, though. You'll also be expected to apply differentiation and anti-differentiation techniques to polynomials.
This all becomes even more important if you'll be continuing maths onto NCEA Level 3 where you have to choose between calculus, statistics, or both. A solid understanding of these calculus concepts from the Level 2 curriculum will make the transition to Level 3 easier.
Calculus, like algebra, involves learning different methods to solve equations and knowing which methods to use and when.
According to the NZQA, these can include:
- derivatives and anti-derivatives of polynomials given in expanded form
- gradient functions
- gradient at a point
- equation of a tangent
- turning points where f ‘(x) = 0 and their nature
- function from a derived function
- rate of change problems (such as kinematics)
Part of the NCEA Level 2 Maths assessment tests a student's ability to use these methods while understanding which ones to apply.
As with algebra, the method to be used could be explicitly stated in the questions themselves or the student may be expected to choose the appropriate method.
Be sure to refer to past and practice papers for the NCEA Level 2 Maths assessments to get a better idea of which kinds of questions are common.
How to Understand NCEA Level 2 Probability Questions
If you know anything about probability, you'll know that it isn't about luck and that certain things can change the probability of something.
To increase the odds of doing well in this part of NCEA Level 2, you should study the concepts that you need to know and strategically revise for the assessments you have to do.
According to the New Zealand curriculum, this unit teaches students how to investigate different situations that all contain a similar element, the element of chance.
Studying the element of chance doesn't sound like you should be able to study, but mathematicians are fairly adept at it. Throughout your schooling and particularly this year, you'll have learned about comparing theoretical continuous distributions, including the normal distribution and experimental distributions, and calculating probabilities using two-way tables, tree diagrams, simulations, and technologies.
The questions for this part of your assessment are based on demonstrating different methods and how to use them, similar to algebra and calculus.
NZQA outlines the following methods so be sure to revise them:
- risk and relative risk
- the normal distribution
- experimental distributions
- relative frequencies
- two-way tables
- probability trees
There's no magic solution to the NCEA Level 2 Maths assessments, but there are ways to demystify the NCEA Maths Level 2 syllabus.
You can't guarantee that everything will appear on the exam, but you can always put the odds in your favour by looking at the syllabus, the curriculum, and past and practice papers when revising.
As always, look to the keywords in the question to see what is being asked of students. Use everything available to you, including revision guides, past papers, and the resources provided by NZQA and NCEA.
In most instances, it'll be important in exam questions to show your working. This shows examiners that you applied the right method and didn't get the answer by accident. As this is often the criteria for the questions themselves, include every step.
It's also useful to show your working just so you don't need to keep track of everything in your head and if you feel you've arrived at the wrong answer, you can simply look back through your working to double check.
The Next Steps for Your NCEA Level 2 Maths
Now, put your knowledge to the test. We can't underestimate the importance of using past exam papers to practise breaking down the questions.
Use the highlighting method we mentioned earlier to outline the constraints, conditions, and limitations of the question.
Once you've answered the question, check that you've really done what's been asked of you. Make sure that you can justify the chosen method in accordance with the wording of the question.
Ask yourself why you choose a particular method.
Being careful and methodical in your revision and your exam is a great way to pass NCEA Level 2 Maths.
Another great way is to work with a private maths tutor. Luckily for you, there are plenty of them on the Superprof website and many who specialise in NCEA Maths.
To find the right tutor, search for maths or the area of mathematics you need to study. From there, you can browse the profiles of potential tutors to see what kind of tutoring they offer, how much they charge, and what their students think of them.
Many Superprof tutors offer the first session for free, allowing you to try a few before choosing which one's right for you, what you need to learn, and how you like to study.
Even if you can't find any local tutors, you can now easily learn just as effectively with online tutoring. In most cases, online tutors charge less than their counterparts who have to travel to their students.
For those on a tight budget, group tutoring is a way for you and your classmates to share the cost of private tutoring.
Be sure to consider all your options. Every student is different, and what works for one mightn't work for another.
