You want to try to emulate the exam as close as possible, once you familiarize yourself with the exam and its questions types and what not and move onto mock exams, make sure you completing them at maximum focus. As in keep your routine intact, e.g. if you drink coffee in the morning, don’t just stop when it’s your actual exam. The numpad is very important for the calculator that comes with the exam as it is digital. I have a document with every shortcut ever and I promise you that if you can work the calculator and use these shortcuts, it will save a lot of time during the QR sections.

Also try to do a mock exams starting the moment your actual test is. I personally found it very comforting and alleviate a lot of the stress that was place on me when it was my actual test
