1. Practice
It's the simplest way to get quicker, better and more confident.
To make your practice sessions as effective as possible, try and work in a quiet, well-lit room that's free from distractions.
Once you've completed a practice test, go back over your answers and note down anything you got wrong or found hard. These are the areas you need to focus your revision on.
2. Think outside the box
To make practicing more fun, try and think of new ways to learn and improve your skills.
You could get a mirror out to work on reflections or find a computer game that involves mentally manipulating shapes.
There are lots of ways to learn that don't just involve reading and working through tests.
3. Use a pen and paper
Find out if you're allowed to take a pen and paper into your test.
Being able to jot down notes or draw changes in a shape can really help you to work out the correct answer faster.
4. Don't panic
It's easier said than done, but it's important to try not to panic. If feelings of doubt start to creep in, take a deep breath and remind yourself that you can do it.
If you don't know the answer to something or you're struggling with a particular area of the test, it's ok to make an educated guess and move on.
5. Keep track of time
It can be easy to lose track of time and spend too long on a question at the expense of questions you may find easier further on in the test.
To stop this from happening, try to roughly work out how long you can spend on each question and stick to it. If there's time at the end, you can always revisit anything you weren't sure about.
