Well there are many great types of math!
I love them all, but my favourite has to be algebra.
I don't really revise for math, but when I do, my approach is always the same.
Write out what you don't know and then write yourself a revision sheet.
Complete that sheet before being tested and it will never fail to get new math into your head.
PS. I'm English, I am now in Year 9 (grade 8) and am one of the top 301 British mathematicians at my age.
I am gifted and talented and also really enjoy poetry, which I have won many competitions with.
I have a MENSA standard IQ.
But you don't need any of that to be good at maths.
Just approach each problem with a clear head, don't feel under pressure and most of all have a great time solving problems!!!!
Math can be fun if you make it that way.
You are your biggest obstacle.
