I was thinking the same thing.Ack! That's a lot of written test to take.
This woman sounds like she's a spitfire and isn't going to quit any time soon until she is able to pass the written test. I have to wonder, Did she even try to backtrack herself on the test to find out what she did was wrong on the test in order to review it and to improve it for herself? She probably did, but still, 771 times is just mind-boggling!
