One of the things you may notice when you do the test is that the way the questions are worded may not be the same as what you have read in the official guide. The information may be paraphrased or 'put into different words.'
For this reason, it's important that you don't just learn the information by heart but that you try to understand what the information means. This will also help you with the English testing section. I am gradually going through the book and making short videos which explain each section.
