I have used the flashcards, and they are quite useful

I have used the flashcards, and they are quite useful. The PDF, as it is in alphabetical order, is somewhat useful as a dictionary; but it would be more useful to me in a spreadsheet (such as in Excel), so that I could organise the words into groups (such as work-related words, numbers, family-related words, etc.) for studying purposes, and so that I could maybe add a column or two so that I could take my own notes about each word. I would definitely recommend the flashcards to others, since they include pronunciations as well as contextual examples of how to use the words.  The PDF I might recommend as a beginner’s dictionary.
