Difficult--if you saw a mistake needing corrected, it was a real challenge to work back to see where the origin was causing it to be unable to change on a particular line. Some questions were not asked until the end, whereas it would have been easier to get those done at the beginning. Worked five hours when it came to reviewing it to send in, and I thought it would be only a matter of minutes after all data had been entered.
