Tip 1: Preparation is key

Start with these materials.
1. The handout exams given by CEM
       Most of the questions in these handouts are patterned from the actual test. Sure you may think that "Im sure nothing will come out of that exam because that review material is given by company conducting the exam. I'll just take a glance at it". This is a common move to make. This is what i did at my first take.
       The technique is most of the part 1 questions that are for I.Q testing are exactly like that of the handout. So since I.Q cannot be memorized, familiarize yourself with the exam. Repeat answering these exams without memorizing the correct answer. After days of doing these test repeatedly you will find yourself answering faster and will be able to see the patterns more easily.
         The technique in test 2 is that if you analyze every question, there would be a particular topic being discussed by each question. For you to easily review these subjects. You can just review the general topic of each of the questions. Almost all of the questions in the actual exam revolves around these topic. This will help you if your already cramming, specially if you only have a basic background around these subjects. As a nurse the part on chemistry and physics was the hardest for me.

2. Google VS dictionary, text books, encyclopedia.
            Most of us are taught not to believe in the internet because of the freedom on how many people can write about any particular topic without a proper body for regulation of their contents making wrong information rampant on the net.But actually Google is faster, easier and more convenient tool for reviewing. most of the subjects you need to learn are on the net. Since I know most of you are cramming  (like me back then) you should use this tool alot. Compare typing than reading the index, searching around the pages for a particular topic in a book you barely read during highschool. 

3. Time management.
             Manage your time. Start the days of your review not to conscious of the time. Established a baseline. Answer all the questions and look how precise you are and how much time it took you to answer the questions. And day by day try to reduce the time and increase the number of correct marks in your paper.  Remember that you may know all of the answers but you need to get to the question first before you can answer. Always try to improve your time.

4. Intelligent Guess
              One way to be intelligent in the exam is to guess the answer. Use the cancellation method to narrow your choices to two and pick one. It is better to have a 50-50% chance to get the correct answer than to be 100% sure you got it wrong.
