This a bottom-up test taking technique, which means you start with the HARDEST questions when your brain (and eyes) have still LOTs of ATP. If you start from the first questions, which are the easiest, by the end of the test you will be exhausted and everything will look very hard.Apply this tip when you do the next practice exam since you need to (re)train yourself to start with the last page of the exam and move your way backwards to the first question.
