If you believe that there are any mistakes with the notes or that there are notes missing, then please contact us here. We advise you to use the google custom search engine for our website on the left to find any notes that you think are missing from this section as those particular notes might be somewhere else on this website. These notes are mostly for the WJEC specification but we have found it difficult to accommodate each specification for each module so contact us if you have a solution or if there are notes missing for a specification that you think should be here. We are trying to make this a maths website for all. Any help or feedback will be appreciated.
