Mixed, sometimes good, sometimes bad. I would concentrate on finding a method of doing the questions as quickly as possible. When I was doing the practice ones I would read the whole passage then answer the questions, but I found this quite slow going as I'd end up rereading the passage about 3 or 4 times during the question answering process. I found it better to read the question then look in the passage for an answer as it usually was contained within one sentence.
