I passed. The pay is abysmal but I can guarantee I'll get paid X amount for Y time spent working so it seems to be the best I have atm. I'll have to work out how to juggle my time between hubbing and ChaChaing.
I tried to get into it a while back, I passed everything but the math part. I'm not horrid with math, but I'm not that great either - I just really dislike math in general. I didn't bother trying it again, the pay just didn't seem worth it.
Making a hub out of interesting questions and your well researched answers will be a great idea I would think. The fact that someone is asking for an answer to it means that people here (On Hubpages) would also be interested in it too.
