Maths Cl [20 characters]?

In year 10 I was with Miss Jones and I was struggling with maths so when I went back to school I got moved down to Mr Smiths cl Miss Jones was a good teacher but I never got it so she moved me down, I get that but the problem is Mr Smith is prob the worst teacher ever and I know he is bad because I had him once a fortnight and I find maths really hard and don't want to fail but hes not very good teacher what can I do? Thank you x
