I find these forms reliable and a steal compared to Scantron's exorbitant charges for their 'official' product. For those having trouble with this: 1) Make sure the students are using #2 pencils. While I've found others will work, it can be hit or miss. Check sample #2 and see if there is a difference. 2) Make sure all labels are dark and within the given rectangle. If the score is too high, your rating engine will think it marked 2 answers. Hope that helps.
