How strong is the correlation between the questions in the leetcode Amazon 50 list and the Amazon online assessment?

The reason I ask is that my understanding is that the Facebook 50 list is extremely representative of the questions asked in a facebook interview, meaning, that if you do the top 100 questions for facebook there is a very high likelyhood that you will see those in the phone screen.

So my question is, how useful is the Amazon 50 for preparing the Amazon online assessment? Meaning, are the questions in the Amazon 50 in the Amazon online assessment?

If not, where is the best place to find those questions?
