I need step by step instructions to install your s/w.

The following steps are for Mac, Windows, and Linux. Not for iOS or Android.

  1. Download etsviewer.jar from and save it to a non-system folder.(Download blocked by your firewall?) You can save it to c:\downloads
    (or /Users/<your_username>/Downloads or ~/Downloads on Mac). After this step, you should have etsviewer.jar in c:\downloads
    Open your File Explorer and see that it is there.

  2. Now, if your system already has JDK installed correctly and if the JDK's bin folder is in PATH, you can simply double click on etsviewer.jar to launch it.
    Mac OS has recently disabled this mode of launching unverified apps directly. So, if you are on a Mac, instead of double click, do CONTROL + click on etsviewer.jar in the File Explorer. This will pop up a menu with "Open With" option. Click on that option and select "Java" from the resulting list of applications. That's it. It will launch the ETS Viewer application.

  3. You may also open a command prompt and cd to the directory where you have downloaded etsviewer.jar. i.e. c:\>cd downloads (or cd ~/Downloads on Mac).
    After this step, you should be on the command prompt in c:\downloads directory.

    Now execute the jar using the following command on the command prompt:
    c:\downloads\>java -jar   .\etsviewer.jar

    This should launch ETS Viewer software.
    (If you get any error message, you probably do not have JDK installed on your machine. Please see this.)

    (This option will not work on a Mac because Mac OS prevents unverified apps from executing directly. You will most likely get a message "Unable to access Jar file.)
  4. You will see the following screen.
    ETS Viewer
    Click on the Full or Trial version of the certification you want to use. ETS Viewer will download the appropriate question bank file from our server and open it.
  5. If you are behind a proxy or if your firewall is blocking ETS Viewer from downloading the file, you may download it yourself from our Downloads page.
    This page has Trial as well as Full versions of all the question banks. License is NOT required to download the full versions. So, pick the one you are interested in and save to any directory.
    Let's say you download JA+ V8 Trial Question Bank and save it to it to c:\downloads directory.
    After this step, you should have a question bank file with extension .ets in c:\downloads

  6. Click on the File -> Open menu of ETS Viewer. It will pop up a File browser, which you can use to browse to and select the Question Bank file that you downloaded.

  7. A License dialog as shown below will pop up. If you are using trial version, just enter your emailid and name and download the license. If you have purchased a license, you may either directly enter the license key or just enter your orderid and emailid and download the license.

  8. This is how it looks after successful installation:

What is the best way to prepare for Java Certification exams using Enthuware tests?

how to improve low scores on OCA OCP Java mock exam
Our Question Banks contain questions organized as Standard Tests. These tests mimic the real test in terms of content and toughness. If you have experience with the technology, you may start directly with these tests. Otherwise, you should first study all the exam objectives from a book. You should also write lot of test programs to solidify your understanding of various concepts.

Once you are comfortable with all the topics, you should start with the first Standard Test. Your score on this test will tell you how well you are prepared for the actual test. You should make a note of all the topics on which you score less and study them from a book. After going through the book, review all the questions of the test one by one and read the explanation for each question, including the questions that you answered correctly, and then attempt the next Standard Test.
Our explanations are really thorough. You should not be surprised to find them more informative than even some books. So please make sure you go through all of them.

Important - If you fail a Standard Test, you should NEVER attempt the next Standard Test before going through a book and learning about the topics on which you scored less. If you move to the next test before doing that, then you will not be able to perform well on the real test.

Taking the same test twice -
You should never take the same Standard Test twice. This is because you will inadvertently remember the answers and you will invariably score a lot higher on this attempt. This creates a false sense of confidence, which will cause you a problem in the real test. Remember, your objective is to improve your score on the subsequent tests not on the same test.

Best of Luck!
