How can I get over my test taking anxiety

I think I am plagued by test anxiety.

I'm a honors maths student, but I'm averaging a C+. I understand completely what the teacher is teaching us. I also take good notes and do the assigned reading.

I get correct answers on the homework. But then when the test comes...I get B's or lower on that.

I try to keep positive thinking but during the test, everything goes downhill. I can't remember the answers, I can't concentrate and all I notice is that my hands are sweating and my heart is pounding.

What can I do?

Thanks
