EOC essay vs real thing

Is it worth it to go through the CFAI eoc essay style questions in depth?

There’s a question to interpret a “1 and 20” fee structure. Are these the types of questions that are on the mock exam?

Good for practice…

But if you’ve done a few of the old exams, it appears the newer ones are more structured.

Whereas the older ones would ask “Name the bias that Jack exhibits and provide two reasons”… the newer ones say “Circle the bias that Jack exhibits and provide two reasons”… And they provide 5 biases to pick from.

would you say the newer ones are easier?
