For me:

Get book on the subject, read from cover to cover and create question/answer in Anki.

When it comes time to refresh your knowledge on the book, just test yourself on the items you added to Anki.

Do you have an Anki to share?

I wouldn't use pre-made Anki files. Creating your own is part of the learning-process. Plus you are the only one who knows what you don't know :)
