If you wish to do some preparatory study beforehand then try working through a GCSE Higher Level mathematics, or equivalent, text book, which may be available online or in a local library. If you have difficulties with algebra, you should consider signing-up for Discovering mathematics (MU123).
You could also help yourself by using a book or website to familiarise yourself with the first core module (that is the first pure maths module, also known as C1) of AS level in mathematics, or equivalent. This will contain some topics which you are not expected to have studied before you start MST124 but, if you can do some work on those as well, it may help you to get a head start with your MST124 studies. [Note that the Advanced Subsidiary (AS) level is used in England, Wales and Northern Ireland. In Scotland, similar content to the AS module above is found in Mathematics Higher, particularly Unit 1.]
You may also like to look at the sections of the following external websites which relate to the topics in the MST124 quiz, such as algebra and trigonometry:
You could also ensure that you are thoroughly familiar with how your scientific calculator works.
