Now my final bit of advice is probably the best bit of advice
. If you really do struggle with Maths and you have tried lots of books, video tutorials and after school clubs and nothing seems to work then get yourself a maths tutor. I know you probably hate the thought of somebody coming round to help you, as you may see this as a weakness, but remember even a short term amount of tutoring for as little as three months can really make a difference! There are many national tuition agencies out there and you can often stipulate what kind of tutor that you want, for example a young or older tutor, male / female etc.
