Dyscalculia: News from the web:
The additudemag blog comes with a self test for adults to see if their math related troubles could be a sign of dyscalculia. They have used a checklist from the dyscalculia.org blog as a basis for this.
You can do this check list on the one from Dyscalculia Services.
You could also do the math and dyscalculia screening test for an online more extensive screening. (use grade 9 if you are an adult)
