I Guess there is a mistake in the answers.
In the Geometry, 2nd part for the triangles, the 4th question - both of the statements alone are sufficient to answer the question, while in the answers the 2nd one is ignored. If someone is interested I may provide the explanation.

By medium/hard I mean 600/700 level questions.[/quote]

So the questions are 600-700 or 700+ ?
In my opinion questions are 600-700 range.
