To study maths you have you have only the way to practise. There is no escaping this reality, to do well in a Maths exam you need to have solved a LOT of mathematical problems beforehand.
Review the problem again and again
If you have made any mistakes, you should review them and understand where your problem-solving skills let you down. Work through the process for each solution.
Have key points of yourself
Remember that Maths is a sequential subject so it’s important to have a firm understanding of the key concepts that underpin a mathematical topic before moving on to work on other.
Understand where you are getting the problem
Once you have grasped an understanding of the initial problem, you can use this as a stepping stone to progress to the remainder of the question.
Keep Confidence on you
Don’t forget that it’s also important to have confidence in yourself and face the exam knowing that you have prepared properly.
