Something I’ve noticed this year after having taken a break from apps and Watson Glazer, is that a lot of questions are repeated. Both from practice tests and between different firms. So spend some time after the practice test going back over the questions to understand why you chose the answer you did, what you’d choose next time, etc along with the reasoning.
Completely agree with AJ’s comment here. In a test I took recently, I recognised 80% of the questions from other tests I had done before! And I’m not applying for 20 firms or anything like that.
It’s very important when you practice to recognise the common “tricks” in each type of question. For example, for the “evaluation of arguments” questions (strong vs weak arguments), they regularly “trick” your brain by giving you an argument that sounds strong, but the topic doesn’t quite match what the question addresses. For example, the question asks “Should X policy be implemented to improve public health?”. If the argument is “Yes, because X is better than the current policy and will help our country save £1 bn” then it’s weak, because it doesn’t address the topic of the question (public health).
Hope this helps and good luck!
