Some of your answers could use some work.
Question 4 on the "expert quiz" is a bit of a stretch. The only thing which really determines market price is supply and demand. Media coverage and technical issues or development may influence levels of demand, but they don't influence the price directly (unless some huge technical issue suddenly changed the circulating supply, such as if ECDSA was broken and Satoshi's coins re-entered the market).
The answer to question 7 is wrong. You sign messages and transactions with your private key, not your public key.
In question 10, Merkle trees are used to verify data, they aren't used to store it.
I also did the expert part and had no problems with technical questions but this one got me as I chose "supply and demand" and will argue that this is what really decides the price.
Saying that media coverage is as important is dumb and makes the whole question look like a joke.
I also took a shot in that intraday price difference question and got it right, but I wouldn't expect anybody but traders to know that. You don't have to be a trader to be a Bitcoin expert!
The 7 was probably corrected already because I chose private key and got a point for it.
So, I got 9/10 right in the expert quiz, but at least 2 questions were completely random and unrelated to your knowledge of BTC.
