The cards are grouped in three different sections (verbs, nouns, other) with each section arranged in order of occurrance in Scripture. This would make individual cards difficult to find, so the set comes with an indexed booklet. A number of blank cards are included for words which may have been missed. (Geographical and personal names are intentionally skipped.)
When I was trying to learn Hebrew, at the beginning of each week I would use the index to find the cards I needed that week. These would go in my shirt pocket so I could review them throughout the week.
The only minor annoyance was that there were some slight differences in definitions between the cards and the text I was using. But this is unavoidable with different authors. Further, this was also helpful in a way, as it showed a second opinion and helped to explain the word meanings.
All in all, it is a very complete, useful tool. Nearly all of the vocabulary I needed (for Kelley's text) was included, and was in roughly the same order as in the text.
