I actually found it fairly helpful and think it's responsible for improving my score. No question bank is infallible, there will be errors are you are invited to report errors to Medify. Whenever I had issues, they reset my account. They even gave me the account for free this year after I complained about last year!
The examples you give only have the word "is" missing from the questions, you hardly have to be a scholar to work out what they're asking for.
