One of the tools you can use in preparing for your NCLEX exam is taking practice test. Remember the saying "practice makes perfect"? Well, it may sound rhetorical to you but it is definitely true in most cases, including studying the NCLEX.
If your study guide or review center includes NCLEX practice tests or mock exams, then you probably made the right choice. This will boost your familiarity with the NCLEX exam and at the same time apply what you have learned so far in your review.
In almost all review packages available online and offline, there is usually a three-step procedure or tests that you may need to take prior to actually taking the NCLEX. The first is a sort of diagnostic test which you will take before you start your review proper. In this test, you or your review center can gauge your strength and weaknesses, enabling you to effectively plan and formulate your study guide. The results of this initial test will tell you where you should need more study and the areas where you can just breeze through in order to manage well you time.
The second sets of tests are comprised of questions styled in the likeness of the NCLEX itself. This test will sharpen your critical thinking skills, which are essential to your bid to pass the NCLEX. You may have to take and re-take these types of exam during your study in order to prepare your mind to the actual test. Remember, practice makes perfect right?
The third is another diagnostic exam, which will measure your readiness to take the NCLEX. The difference between this diagnostic exam from the first one is that now, it assumes that you have studied and reviewed whatever materials you have. It will also gauge if you have worked on your weaknesses and further reinforced your strengths.
If nothing changed, then you better go back to your study plan and rethink everything. If that didn't work, you should seriously start considering making drastic changes or a total overhaul of your study guide. In any case, don't panic. It will really not help your cause.
