I took it and didn't pass it either by 3 points. I haven't done any math for almost 12 years. I didn't think it was hard, its just that I didn't know it. I tried teaching it to myself in two weeks using the following websites that I thought were very helpful. I was rushing myself and I think if I would have studied for about another month, I would have passed.

From what I've been told, if you know how to use the Scientific Calculator, then you should be able to pass the test with flying colors. I took my test with just scratch paper because I didn't know how to use the Calculator.
Good Luck,
