any smart 12 year old could easily pass the GED
The GED was a hard test back then because it was supposed to show the student actually would have been able to graduate from a rigorous high school education. I have no idea of how hard it is now. There is also an alternative test to the GED, but I’ve been out of touch with Adult Education for some time.
I hate to point this out. Fractions are easy. Express it as ounces of weed. You would be amazed how many of the brain dead already know fractions well.
About 6 years ago, many schools began replacing the GED with other tests that are supposed to be more difficult. So... maybe, after you taught, the GED got easier (?) and then states decided the test needed to be more difficult again (?). I don't know. Maybe you will know: Here's the math covered on one of the newer tests.
