I would like to start to use one of the CorePlus decks but would like delete the words I have already learned from reading books. I can get down to 15,000 words in the Core Plus deck by excluding Core10k cards (already finished Core10k) but I have an additional 10,500 word deck I would like to compare to the remaining cards. The two decks have different schemas. Is there any easy way to remove duplicates between two non-matching decks? I also have at my disposal Excel 2013 and Open Office if I can somehow do it that way. I am not very skilled with spreadsheets though and would need some help if that is the only route to pursue. Thanks!
