I took it today and got a 147. I was asked to be the HS Math teacher in November, and have until 4/30 to pass the 5161. My background is Music Ed (long story), and I've been out of Math for over 40 years....yes, I'm that old. I used the Cliffnotes book as well as KhanAcademy to study, but will look up the freetech4teachers site, also. Any advice is appreciated!
